Patrick - LED Taillight problems

[patrickt]

Remove the two fast blow fuses adjacent to the trailer relay, leave them out, and hit your brakes, and turn on your turn signals. Do any rear lights at all come on? Do the front lights behave as expected?

I'm through for tonight - will try that tomorrow.

Thanks

Alright, we'll continue "splitting apart" the circuit until we isolate the portion that is causing the misbehavior. For the next step, you will need a simple 12v test light, not a VOM. Assuming the car's lights act normally with the fuses pulled, we'll put a new bulb load on the trailer side of the removed fuses and see if they just come on normally or whether the misbehavior is present even without the rear lights wired but with just a 12v test bulb
