Trailer= I'm stumped

[Jmnhunter]

alright, it started like this: original lights-drivers side worked at all elements, passenger side not at all. bought a new kit and its a standard wiring kit from blazer for a 17ft trailer total length, turned on the headlights, and both drivers side and passenger side works -good so far. tested out the 4-ways only drivers side worked, same with the brake lights -passenger side did not work at all..

so what i did so far to figure out the passenger side:

-new connections towards the passenger side lights (3) =nothing different

-kept the headlights on with the flashers going and it worked but it was a weaker flicker from the passenger side than the drivers side.

-put a 4 way tester for just the truck connections and everything worked

-tested the old drivers side assemblely with the passenger side wires and the same thing happened-running lights worked but no brake or four ways. (it worked fine when it was on the drivers side)

what do you think? bad trailerlight assembly?

Just an thought. Do you have the wires to the Taillight and brake/turn signal switched around. If so, the turn signal will look dimmer because the tail light filament in the bulb is the one blinking. If this is the case when just the taillights are on that bulb should look brighter then the other one as well.

Sounds like it's probably a ground issue but if that's all checking out just something else to consider.

walleyeman; no wires switched around, i checked that, but thats good; i think i will splice a ground wire from the white wire on the connector and bring it back to the rear and bolt the wire on the rear of the assembly

Another thing you might check is the ground wire inside the light assy itself may be loose. Take the cover off and verify it's snug / tight.

I'm sure it's been stated but make sure your ground contacts are cleaned up. I take a grinder and make sure the trailer surface where the ground bolt which is built in to your light assembly connects and makes contact to the trailer is cleaned up "shiny" real good.

Thats for each light and ground source including where the white ground wire is connected to the Frame up by the plug-in and coupler.

Hve you tried checking the bulb socket?
