I have brake lights and turn signals on my trailer that work fine, but the tail lights don't. The first thing I did was check for voltage at the plug on the vehicle with a volt meter and everything is good. So, I spent a bunch of time on the trailer. I can't find any problem there. I plugged the vehicle into another trailer and had the same problem, so it must be the vehicle. I even check that the plug had continuity.
Can any of you 80 experts/problem solvers/electrical engineers tell me how I could have power to the plug (as per my volt meter) but not have power transmitted!?
