low beam not working (pt. 2 of 2)
Hereís where I phone a friend/family member. I had to pull out the multimeter and test each socket to see if power is getting to the light unit. Since I donít know the specific voltage each light unit is supposed to get, I mirrored/matched each voltage from the passenger side against the driver side. Here is an image/paint Iíd sketched together for yaíll. I am not an electrician and I hate testing wires. Also, here is a wire color to letter diagram (your colors may vary).
Passenger Light Wire Harness
B-TAN w/white stripe
C-GREEN w/white stripe
D-BLUE w/white stripe
Driver Light Wire Harness
D- BLUE w/white stripe
With both light units/assemblies removed (driver and passenger side), I turned on the lights, and tested each male pigtail on the passenger side, and then tested the driver side, and wrote down my results for each wire. Boom. Found the bad wire, and wouldnít you know, itís the same exact wire that delivers power to my driver side low beam. Now that I know this, I would have to trace that wire back to the fuse box and look at it. but that requires removing the fuse box and pulling out other things that I did not want to do. The last thing I need, is to cause more damage to wires.
But wait. What if the wire isnít the problem? Maybe itís the actual male pigtail connector. This would mean, I would have to remove the pigtail head connector, and replace it. (there another forum I read here that a gentleman does a really nice description on how to replace it, but that required soldering. Not looking to spend money on equipment and, as mentioned, I didnít have that time).
Maybe itís not the connector. Now I had to test that (yellow) wire to see if power is getting to that pigtail connector. I have some wire strippers and I peeled away a little bit of the insulator to expose wire. With the multimeter I measured the voltage (with the lights on) and still not voltage. CONFIRMED. POWER IS NOT GETTING TO MY LIGHT AND WIRE IS BAD, but the connector is still good.
Here is what weíve all been waiting for. Well what the heck did you do? I basically spliced into the power supply from the passenger light. Meaning, that I cut the (tan) low beam wire to the passenger side and added the driver low beam wire (yellow). With a wire cutter and 22-16 gage heat shrink slice connectors (wal-mart) I GOT MY LIGHT TO WORK!!
Sadly, this is only a temporary fix, and this doesnít resolve my real underlying issue. When I come around to it, Iíll post a follow up once I have more time on my hands or if this temporary fix fails.
