Trailer ?

Big Muddy rancher · Posted: Tue Aug 31, 2010 5:57 pm Post subject: Trailer ?

The light on my brake controller will not light up. It is supposed to when the trailer plug is connected. I seem to have power on two prongs on the truck side of the plug. Is the brake feed different then the brake light feed?

The light will not light up unless you have a complete connection to the brakes. I'd start with the plugs on the truck and trailer. First use a test light on the truck if the light on the brake control lights up your good back to there. If thats the case I'd take apart the plug for the trailer and see if the wire came loose. If that checks out start looking for a broken or corroded wire. Make sure the trailer is grounded good to the truck most trailers ground thru the ball and with the fold down and turn over balls rust will hinder your ground.To check for a good ground hook up a jumper wire from the trailer to the truck.

Thanks Denny, I have all my lights working and I can use a jumper wire to apply the brakes. It must be up the wire loom where it's not making connection(oh fun), I started peeling back up the line looking for the break.

Thanks again.

I wasn't worried about lights but brakes are a luxury i kinda enjoy. Shocked

Don't get me started Gcreek. My son borrowed the truck to tour some girls around and it came home plastered in mud and the trailer brakes wouldn't work when i hooked it back up. Not say but mighty suspicious. Confused

Denny would their be a circuit breaker that could be bad on the brake line? I can't seem to find any problem with the wire.

I would check the brake feed wire where it goes into the plastic connector where the wire's branch out to the tail lights and plug. It's just under the bumper on the rear left corner.Those brake wires will corode going into the plug I just cut them and bypass the plug. It's best to soder the connections and put some heat shrink over the connections.If you don't they'll quit working some cold day in January.
