Workbench Task Lighting using Armacost LED Strip Lighting

It's been a busy summer - I haven't had much time for posting - so I figured I would get back into the game with a pretty simple one. I wrote earlier about my garage organization project using Ikea kitchen cabinets - full height wall cabinets, combined with upper wall cabinets above my table saw, mini fridge and mini freezer. You can check out that post here. 

Completed Installation - LED Strip Lights underneath wall cabinets, lighting work surface / freezer
The table saw and freezer make a pretty handy worktable when I'm not using the table saw. I thought I would add some task lighting over the table saw, and decided to try out Lee Valley Tools new LED strip lighting kits. They have all kinds of options - white or mulicoloured LEDs with various LED spacing for different intensities, and transformers of various capacities to match the current requirements of the installed LEDs. They also have some dimmers, switches to round out the installation. I made my lighting plan, decided to go with white LEDs with a one LED every 1/2 inch spacing (high intensity) and the appropriate transformer.

Power Supply Mounted in the Wall Cabinet - with all my tool chargers
The LED light strips are high quality - you can select between two different white colors - warm or natural white - and the light strips come with a 3M adhesive backing to apply directly to the application surface. I decided to go with the natural white in the garage, and the light is bright and clear - perfect for task lighting. Prior to application of the light strips, I used a bit of brake cleaner on a rag to clean off the melamine lower surface of the Ikea cabinets - just to ensure I would get good adhesion. This worked fine - 18 months following installation the LED strips haven't moved or delaminated.

The Lee Valley Kit comes with connectors to allow you to cut the strips to custom length
I decided to control the light strip 30W transformer with an Insteon switch for automation control, and installed the switch and a two plug outlet in a 4" junction box using a twin outlet cover plate. This way, I got 2 electrical outlets above the table saw. I mounted the transformer inside the Ikea cabinet on the plywood board I installed for all my cordless tool chargers.

Conclusion

The Lee Valley LED light kits are top quality, very versatile with many options. I have above average confidence that if I need to repair or modify this installation, I'll be able to get parts or components from Lee Valley in the future. The finished installation is neat and professional looking, the light quality is very good and suited for the application. All in all - very satisfied with this product.

BMW 535xi Touring E61 Tailgate Wiring Harness - SenCom Repair Kit Installation

My BMW 535xi Touring is a 2010 model manufactured in March, 2009. Almost 6 years old with 120,000km. Last summer my remote locking failed – and it wasn’t the diversity antenna module under the rear spoiler, so I suspected wiring issues. I took it to the dealer to have them check it out – and they charged me about $500 to re-splice about 6 broken wires on the right side hinge harness. Since they didn’t insert a repair section – I was sure that this problem was going to reappear, and from what I’ve learned on the forums, I decided to try out the Sencom repair harness kits – with silicone insulated wire for better protection from repeated flexing, particularly at low temperatures.

Melted rear window defroster ground wire (far left) and cracked tailgate lights / locks ground (far right)
This fall – at the onset of winter – I noticed my rear window defroster wasn’t working. I suspected a broken wire in the defroster circuit, so I knew it was time to get at the harness repairs.

I ordered the kits through Autoteilemann.de – very quick and easy and the DHL shipping they quoted included all the taxes, duties and brokerage charges. It took about a week to receive the kits. I ordered 3 to be able to do a complete harness replacement – left and right. There is the kit for the right side harness, and 2 kits for the left side harness – one for the electrical wiring, and one for the antenna cable and windshield wiper fluid tubing.

Left side SenCom Kits Antenna Cable and Washer Tubing - P/N ANT0612 (left) and Tailgate Harness P/N 2016062 (Right)
The kits came with everything required for installation – all the butt crimp connectors, heat shrink tubing where required, new terminals for the defrost attachments on the rear window, terminals and terminal housings for the antenna cable splice and diversity antenna amplifier attachments, washer fluid tubing and barbed tubing splice fitting, and the rubber boots for the tailgate wiring pass through on the left and right sides of the rear window – pre-installed on the wiring loom.

Crimps, Antenna Connectors and Shells, Heat Shrink, Tubing Connector supplied by SenCom with the Left side kits
In preparation for the job – I only had one tool which I needed to add – a crimper for the very small insulated crimp connections. I picked this up at an electronics supply store. Otherwise, for tools, I used a Klein stranded wire stripper (red handled) for all the wire stripping, and an insulated channel lock multipurpose crimper for the standard red, blue and yellow insulated butt crimp connectors.

 I heat shrunk all the connections under the rear spoiler around the diversity antenna amplifier to ensure no moisture would get at any of the connections, so the heat gun came in handy there. When doing both sides – you’ll have about 120 wires to strip over the job – so make sure your stripping tool is sharp and in good condition.

I followed the Sencom video on Youtube to guide me through the process – very thorough. Here's a good tip - when the instructions come up in the Youtube video in german text - use your iPhone or Android Google Translate App to translate this text immediately - I was really surprised at how well this worked. The translation was never perfect, but you could get the idea fairly quickly.

Google Translate App is your friend with the German language text in the SenCom video
Start by opening the tailgate and opening the window glass first, then by disconnecting the battery negative post. I waited for the car to go to sleep mode prior to disconnecting the battery – about 10 or 15 minutes. I placed some small rags in the catch for both the tailgate and the window to prevent them from latching during the job.

Rags under the window and tailgate latches will help keep you moving - so you don't have to manually unlatch these if you accidently let them close. You'll be opening and closing the glass and tailgate many times during this repair, especially if you're doing both sides.
I started on the right side – removing all the trim panels per the Sencom video exposing the harness between the tailgate and the windows. I also made sure to let the car warm up in the garage overnight - so that the plastic and wiring wouldn't be cold and brittle.

A trim removal tool will help keep you from breaking the plastic.
When it came time to remove the curved black wiring supports in the hinge – I used a piece of wire coat hanger to push the pins out of the plastic clips retaining the wiring supports – makes removing these clips much easier.

Mini screwdriver worked on the outside hinges to remove the locking pin of the clip holding the black wiring guides
A short piece of wire coat hanger was flexible enough to get at the inside hinge pins - where the screwdriver couldn't access
The trim removal tool was perfect for removing the clips once the locking pin was pushed out
Removing the wiring guides was a bit tricky - using a rag to help protect the paint was a good idea when coaxing the wiring guides out from inbetween the tailgate and glass hinges. It can be done without loosening the bolts on the metal hinges.
Removing the black wiring harness guides - protect paint with a shop rag
Plastic storage container for keeping trim hardware in the order of removal - makes replacing the hardware much easier as you put everything back together in reverse order
Cut the old harness, splice in the new harness on the right side at the tailgate – then remove the speaker in the roof just ahead of the window hinges to access the harness on the inside of the car.
Carefully separate the OEM cable boot from the cable wrapping, and slide up and out of the way
Cut the harness - 10cm / 4" of free cable gives you lots of space to perform the splices
I upgraded the larger gauge splices (blue size) with heat shrinkable crimp connecters that I had on hand
All cables crimped on the right side talegate harness - and waiting to test. Note the number labels on some of the wires to uniquely identify the conductors in the SenCom harness that have the same gauge and color
Pull the old harness through the hinge area, cut the old harness out leaving at least 6” of the old harness to give you space to make connections in the speaker area. Pull the new harness through the wire boot underneath the speaker area, and make all the splices in the speaker area.
Both right side SenCom harnesses pulled through the body cable boot up from behind the inside rear speaker - I used electrical tape on the SenCom harness to make pulling the harness through the boot go easier. Then I removed the electrical tape to perform the splicing
Then go on to do the same for the harness running under the rear spoiler in the diversity antenna amplifier area. The connections under the spoiler are where I ran into a slight issue – one of the wires is brown with a very thin blue line – I mistook it as a ground wire and didn’t track it in my splicing. I had to go back, cut the splice I had done inside the car to identify this wire to the other end of the harness in the diversity antenna area.
Right hand side cable splicing in the speaker opening.
Harness Splicing Complete on the Right Side
A good trick for working with the factory harnesses after you've removed the adhesive tape wrap - is to remove all the residual gum from the wires with Goo Gone before starting the splicing. This will help keep your hands clean during the crimping.
All the ground wires – straight brown with no stripes in the factory harness – can connect to any other brown wire of the same gauge in the harnesses – you don’t need to match them to the same ground wire exactly. Otherwise – obviously – all the colored wires need to be connected correctly. The Sencom harness has a series of wires of the correct gauges but some wires are duplicates and you’ll need to track the duplicate colored wires with a continuity meter – so that you can identify them individually and track the connections. To get this straight – for each harness I cut and spliced – I wrote out a list of every wire – primary color and stripe color, and matched it with a particular color in the Sencom repair kit – e.g. Red wire no. 1, Red wire no. 2., White wire no. 1., White wire no. 2. Then when I made the matching connections at the other end of the harness – it was simple to get everything matched up correctly.

With the 2 harnesses completed on the right side – I moved over to the left side and followed the same method for the tailgate wiring harness, then did the diversity antenna cable / washer fluid circuit / defroster ground wire harness. This is where I found that my defroster ground wire had completely melted through.

To splice the antenna cable – Sencom provides you with a matching pair of male and female OEM style RF connectors – which were fairly straightforward to install. You have to strip the antenna cable in three stages – the outer cable insulation, the inner shield wire, and then the signal conductor insulation. I judged the strips and cuts based on the old connector – and on the female conductor, you need to crimp on a special, tiny, female signal conductor pin. A bit tricky. I managed to get this right – eventually proven by good radio reception and lots of channels when I got everything back together and tested.

Once everything was reconnected – and prior to reinstalling any wire guides or trim panels, I reconnected the battery and tested everything. Signals, brake lights, parking lights, reverse lights, license plate lights, defroster function, radio, central locking, cargo cover release, tailgate release, window release. Everything worked perfectly the first try. No fuses blown.
Test all functions prior to re-installing the rear spoiler, or replacing any of the harnesses or trims.
So then – I disconnected the battery again just to avoid any possibility of a short circuit while replacing wires, and tucked away the wires and reinstalled the trim. The wire guides next to the hinges were a bit tricky to get back together, but I got everything clipped together and tightened the guides with a set of pliers so they would hold together firmly. I touched up any small scratches on these guides with a black Sharpie, so I looked like new when it was all back together.

I pulled the new harness through the boots in the roof just forward of the hinges so that there would not be too much slack in the harnesses ahead of the hinge wire guides – so the harness would not be able to be pinched in the hinges. Then I double checked the opening and closing of the tailgate, window and made sure the harnesses were moving freely without pinching. Then – tucked the splices up underneath the speaker openings, replace the speakers and trims, and reconnected the battery.
So – with the repair completed, I noticed that my remote locking / unlocking range became much better. I was down to being able to lock or unlock the car within only about 10’ of the tailgate. If I was at the front of the car, I couldn’t even unlock it. The broken ground connection for the defroster circuit may have been the cause of the lack of range of the remote locking circuit.

Conclusion

Radio reception was excellent, with lots of channels and maybe more channels than I had before (better reception?). It also seemed like comfort access was working a little bit better as well.
Repair time – about 12 hours total. 4 hours the first day, and 8 hours straight the second day from start to finish. Hopefully I won’t have to go back into this for the entire time that I own this car. This is clearly a design deficiency, hopefully BMW corrects this in future variants it builds with tailgates. 12 hours is a lot of time to spend on this – but I love the car and hope to keep it for a while (hopefully until BMW imports a future 5 series touring to North America….)

4 Year Update

I've been running this repair for just over 4 years now - and it's been solid. No futher issues, no problems with any of the tailgate lighting or functions. Rear window release and defrost still working great. All good. Impressed with the quality of these kits.

The Sencom kits were a bit expensive to have shipped from Germany with duties, taxes, brokerage, etc. but the kits are excellent quality. I can confirm the kits work fine with North American vehicles (535xi Touring LCI e61) with one spare conductor on the right hand side, and one spare antenna cable on the left hand side. Thanks to Sencom for supporting us with a quality repair kit and an excellent instruction video. Thanks to everyone on the various BMW forums for your support, I've gotten lots of good feedback on this post and I appreciate it.

Delta Vertical Wall Mount Bike Rack - from Lee Valley Tools

It's been a while since my last post - this spring has been exceptionally busy with the basement insulation project, basement floor slab crack repairs and concrete floor painting, the variable speed pool pump motor upgrade, and the 2" pool plumbing upgrade. I still have to write about the pool projects, but first I wanted to show some photos from my bike rack upgrade in the garage.

The completed installation - adult bikes mounted vertically on the wall - kids bikes parked underneath. Very space efficient, and easy for the kids.
The new house had a series of hooks on the ceiling - 10' off the floor, and over the railing next to the stairs to the basement. To lift a bike up or down from a hook, you would have to get close to the railing, and stretch to get the front or rear wheel on or off the hook on the ceiling - a real task. The bicycles would pivot on the hooks, and bang into each other - pretty frustrating at times. I wanted a solution that would keep the bikes off the floor - we need all the floor space to park 2 cars at times, and help keep the space neat.

The previous storage rack - bikes would swing around, handlebars would hook, not ideal.
I did a bit of research into vertical wall mount bike racks - there are some interesting designs - then I found these at Lee Valley Tools. The great thing about Lee Valley Tools - reasonable prices ($21 each), quick and inexpensive shipping (frequent free shipping promotions) and quick delivery. So - I ordered six and they arrived in 2 days.

Delta Cycles Vertical Bike Rack with Tire Tray
If you look at other vendors - sometimes they will sell the rack and the tire tray separately - the Lee Valley Tools packaging includes both for one price.

Mounting the racks was simple - I found my wall studs were spaced 16" - and decided to lay out all four racks for the adult bikes - 2 road bikes, 2 mountain bikes - on 16" centers with staggered heights so the handlebars wouldn't interfere with each other. 

First bike installed. I used a Laser Level to get the top and bottom trays vertically aligned. 
Here's a photo of all 4 bikes installed - 16" centers. This turned out to be perfect spacing. 12" spacing would not have been enough (although it might have worked if you need a very tight installation).

4 bikes - 16" centers
The bike hooks are solid, support the bikes well. I'm careful when installing the bikes on the hooks to let the weight down slowly on the hook, to make sure I don't over stress the wheel rim. The upper rack installs with two 1 1/2" screws provided with the kit. These screws are a bit too short if you're installing on a stud wall with drywall - you'll need longer hardware for a solid installation.

The supplied hardware is too short for drywalled walls - these screws are only suitable for mounting directly to wood studs.

And here's a photo of the bottom tray. The bottom tray mounts with self adhesive tape - no screws required although screw holes are provided.

Note the vintage green Michelin Wildgripper Sprint S tires - Kevlar beads, super light, and now getting very old and brittle. Time for new tires.....
In summary - good quality racks, very good price, simple installation, clean look when storing bikes - very satisfied with this system.

Basement Concrete Floor Paint - Single Part Epoxy Paint

Our 25 year old house has (had) a concrete floor in the basement utility room that was a bit more than rough. A spiderweb of hairline cracks, and some surface abrasion / weakness caused by lack of maintenance and efflorescence in certain places. It looked like the concrete had been painted at one time, but it was very difficult to tell.

The completed floor paint job.

Concrete prepared for painting - all cracks filled with Sika Epoxy Crack Fill
With the basement insulation project, where all the perimeter walls had to be cleared so that the drywall could be removed, and spray polyurethane foam insulation applied - it was the perfect time to paint the perimeter of the concrete floor. Prior to paint, I repaired all the floor cracks with Sika Crack Fix - from hairline cracks to the largest cracks which measured approximately 4mm wide at their widest. 15 tubes of Sika Crack Fix - $300 worth of epoxy - and all the cracks were filled and the floor ready to paint.

Cracks repaired that run into floor sump
For a concrete floor paint job, I highly recommend that you have a belt sander - it's perfect for smoothing out any surface roughness, high spots on epoxy crack fill, and buffing out any surface imprefections due to efflorescence. Since I just need a belt sander for this project, I bought an inexpensive Skil 3 x 18" belt sander - the 6A 7510 with pressure control. It's a nice tool, and was perfect for this job.

For paint - I decided to go with a simple single part epoxy. I did not want to get into two part epoxies requiring mixing of part A and part B - since I wouldn't have any heavy loads or vehicles on the floor. I also wanted a brand name product with a good reputation, commonly available at local building stores - so that I could restock easily, and hopefully procure the same product for touchups every couple of years.

I settled on the Kilz single part epoxy concrete floor paint - reasonably priced and with good online reviews, from a good manufacturer.


Kilz Concrete and Garage Floor Paint
I had several spots with efflorescence - a white crystalline staining in several spots on the floor - particularly around 3 or 4 concrete columns supporting the garage elevated slab. I chose to simply wash the efflorescence with the concrete wash product recommended by the paint instructions - KILZ Concrete & Masonry Cleaner & Degreaser.

Following the first coat of paint, I found that any places I had raised epoxy repairs, and I hadn't sanded the epoxy - I didn't get a particularly good bond of the paint to the epoxy. So for some spots, I went back and sanded down the epoxy crack fills with the belt sander, which also roughened the epoxy and improved adhesion of the paint.

Sanding down Epoxy crack repairs flush with the concrete
I also found that where I had heavy efflorescence stains, and I only cleaned with the KILZ Concrete & Masonry Cleaner & Degreaser, the paint puffed up as it dried, and gave very poor adhesion. So it was clear - I had to do a better job dealing with the efflorescence prior to painting.

Halo of efflorescence around concrete column - led to poor adhesion.
At the spots where I had poor adhesion - I used the belt sander to take the paint back down to the concrete, and physically remove any efflorescence from the surface. Then I used the recommended concrete etching product - KILZ Concrete & Masonry Cleaner & Etcher. This product was aggressive on the efflorescence, and soaked into the porous surface of the concrete - bubbling and hissing whereever it encountered the efflorescence. I then cleaned with rinse water, and let dry for 24 hours. When I went back to inspect the concrete - the concrete was perfectly clean, dry and natural coloured, except in a few spots where there was some new white efflorescence on the surface of the concrete - much less than before. So at these spots - I did a second treatment with the KILZ Concrete & Masonry Cleaner & Etcher, and waited another 24 hours. Following the second treatment, I had no further efflorescence on the surface of the concrete.

Efflorscence repair - sand down the paint, remove the efflorescence with Concrete Etch, and repair weak surfaces with a thin layer of Sika Epoxy Crack Fix
So - I then applied a second coat of paint - and so far - it seems to have beat the efflorescence, no puffiness or lack of adhesion in the paint, and better bonding of the paint to the epoxy crack fix.

Finally - I had spots of the concrete floor where there were small sections - up to a foot long by 6 inches wide - where the surface of the concrete had started crumbling slightly, leaving a rough surface. At these spots, I used Sika Crack Fix applied across the surface, spread out with a putty knife, and sanded flat with the belt sander once cured. This protected the concrete surface, and gave a nice smooth surface for the paint to adhere to.

Rough surface repair with Sika Epoxy Crack Fix - levels chips 
The final product look much much cleaner, and neat. A huge improvement. A bit of an investment in time and effort, but I think it should pay off when it comes time to sell the house.

Final floor repair
