running lights,tail lights,and brake lights quit working on my motorhome?

Question

I have a 1987 Rockwood (Driftwood) the running lights,tail lights and brake lights quit working yesterday. The turn signals and headlights work. I checked the fuses and they're o.k. any suggestions?

Answer 1

Wiring on motorhomes is a genuine nightmare, even if you have the factory diagram(s).
The MOST PROBABLE cause is going to be a bad ground wire. The reason the turn signals still work is that they are gaining ground source by following the filaments from the other lights. The others cannot use the turn signal circuit because the switch interrupts the circuit.
Easy to test -- either use a jumper wire to ground one of the lamp assemblies and see if it will illuminate.
If you have a test light, turn the lights on, and use the test light to complete the ground circuit at one of the lights. If it comes on, there is no ground. If this is the case, you are going to have to locate the MASTER ground for the body skin.

Good Luck and Merry Christmas
