DEISWERTH Posted October 2, 2007 Posted October 2, 2007 Need a little help with my trailer lights please push brakes-lights work. turn lights on, parking lights/side marker work-push brakes they go out? turn signals work w/lights on or off-push brakes they go off? Is this something to do with my brakes, my tow vehicle, ground, or something else? Thanks for an help. Doug Quote
Flatfish Posted October 2, 2007 Posted October 2, 2007 Sounds typical of a grounding problem, run a ground wire from the trailer to the truck and check the lights out again that should confirm if that is the problem. Use one half of a set of jumper cables for a quick check. Quote
2000WHITEGMC Posted October 2, 2007 Posted October 2, 2007 I just had this problem and the ground was loose. Sanded off the rust and paint around the area it is grounded on the trailer shot di-electric grease on it and cranked it down good and tight. Works like a charm now. Good luck. Quote
