Reposting to this site, sorry if youíve already seen it.
Ok folks, I am towing a Ford C-Max with my 2018 THOR ACE 29.3. I installed the wiring for the tail lights, breaks and turn signals from a kit I purchased from eTrailer. It uses diodes to tap into the existing rear lights of the Cmax. Its a combined system with turn signals and breaks on the same circuit. I keep blowing the number 22, 20 amp fuse (its in the panel right by the steering column on the Ford F53 chassis). This fuse controls the turn signals and breaks lights to the trailer hitch. All lights on the coach always work fine, the 12 volt trickle charge to the Cmax battery always works and the Cmax running tail lights always work when connected to the coach. I replace the fuse itís works for a while then when I stop and check the turn signals and break signals to the Cmax will be out at some point during the trip. I have connected the ground to a ground post the Cmax has in the engine compartment. I have checked and rechecked every connection and I cannot seem to find the problem. Iím looking for suggestions and any help would be greatly appreciated.
