Is This A Valid Assumption?
Another weekend wasted chasing electrons!
If when hooked up to one vehicle the trailer lights function as they should with no anomalies with the trailer lights or vehicle lights and then when hooked up to another vehicle the vehicle's backup light come on when the other lights come on, can one assume that the trailer's wiring is OK and the problem lies with the vehicle's wiring?
I can not figure out how voltage can be getting to the backup light just because the trailer is hooked up. Can someone DRAW me a picture?
