New here, first post. I'm having an issue with my trailer lights not working. The brakes work and the breakaway battery charges, no lights though. Tested the the trailer lights at the trailer plug with a 12 volt power source and they worked. I have no ground on the truck side when measured with a meter (not sure how the brakes work). At the truck, I put an analog meter (positive lead to the +12) and (negative lead to the Left or Right tail lights) and got 12 volts with the hazards on. Everything worked last year, but I pulled three other trailers between then and now. I think it is a fuse issue, but I can't figure out which fuses are tied to the trailer light operation. I found 3 fuses I could tie to the trailer by the abbreviation TRL, and 2 were blown. I replaced those and still no lights. Any ideas? Are there any other fuses tied to the trailer? Thanks in advance for any advice.
