So, I had a bit of a mishap that ended with severe damage to the 7-way cable on my travel trailer. I installed a new one only to find that while I have running lights and trailer brakes, neither left nor right turn signals/brake lights are working. Checking the voltage at the factory connector on the truck, I am finding 12v at the running lights (which I expected) and 5-ish volts at the trailer brakes with the gain set low (does this sound right?). Both L and R turn signals are registering .8-1.2v, with the brakes applied. These findings pretty much mirror the results I am seeing at the junction box on the trailer with the new cable installed.
I haven't had a chance to dig into the fuses/relays, but I assume that since I'm getting some voltage at the turn signals that I will find the fuses to be good. Would fried relays cause these symptoms? If so, can I pull another known working relay and swap it out to test - if so, which one(s) would be compatible? Also, if the relays are shot, do I need to buy specific ones (Turn signal) to replace, or are they multi-purpose? If the relays prove to be functional, where should I be looking next?
I apologize for the dumb questions, but electrical troubleshooting and components are parts of a skill-set which has always eluded me. I very much appreciate any insight.
