Tow Light Wiring Problem
Short question - any suggestions on where to start looking for current disruption that occurs when the headlights are on?
Long version - After several years of flat towing the jeep with magnetic STT lights on the bumper, I’ve now have some sort of circuit disruption. Turning on the coach headlights or running lights, causes the jeep STT lights to no longer function correctly (or at all).
With coach lights off (daytime),
Brake – ok
Left or Right – both ok
With coach lights on (full on or running lights only)
Running lights – OK (but they seem dim, hard to tell in daylight)
Brake – nothing
Left or Right – slight flicker in both sides at same time
I’ve taken apart the tow wire receptacle at the back of the coach (by the bumper), all wires were tight.
I’ve put a test light/prongs in that receptacle at the back, got similar results – good signals with the headlights off, no signals with the headlights on.
Suggestions?
