I wired the trailer lights
, and this is the report:
Good News- Flashers work
Turn Signals work
Outer Stop ( brake ) lights
Bad News- Inner stop (brake) lights
Nightime lights don't work
Side markers don't work
Car's headlights didn't work also. We unpluged car from trailer, replaced blown fuse, and lights worked. Connected back to trailer again, and lights didn't work again and fuse blew again.
So there's a problem with the white or brown wire. The trailer plug originally had a short white wire coming off it; I had previously attached this wire to the license
plate of the vehicle, and all worked fine.
I had the brilliant idea to attach a long piece of white wire to the short stub, run it into the trailer and attach all the white wires from side marker lights and tail lights
to it. Also, I connected this white wire to a trailer frame bolt as a 'trailer ground'.
So where did I goof? I guess I don't understand the principle of the white wire and 'grounding'.
