Trailer light problems

I've got an intermittent problem with my trailer lights - either one side or the other will light (tail lights and side marker lights). This is intermittent - sometimes both sides will light. I put a test light on my truck's electrical input - that doesn't seem to be the problem Any suggestions on where to start troubleshooting? Thanks much. Grounds can be a problem but don't ignore that cheap assed connector most trailer lights hook to the car with. Trailer lights always seem to be trouble if they are out in the weather and dunked in the water.. I have mine on a 1x4 that I keep in the garage and I bungie it across the back of the boat when I tow (or just to the trailer if I am going "bareback"). The wiring is SJOW cord, not that zip lead the trailers come with. I agree ... mainly because I am not so sure the OP's problem is a ground. Usually there is only one, common ground connection to the trailer. Since he stated that either one side lights or the other ... sometimes both ... it would seem to indicate that he has a ground connection. Betcha his problem is in the connector plug. Eisboch Or where it's spliced into the car/truck harness. My last answer doesn't make sense. The left side/right side isn't determined in the connector (except for turn signals). It's in the trailer wiring, if at all. The four pin connector has +12v for the running lights, left turn, right turn and ground. The +12v should be "Y'd" to the left and right side running lights. If some how that connection is hosed up, that could be the problem. |
