No amber lights. Diodes are in the right place. This morning, just for giggles, we installed a light bar that keeps the wiring separate from the jeep. Turns work, brake works UNTIL you turn on the coach lights. At that point turn signals and brakes do not work on either vehicle. Scratching our heads in frustration.
Just for giggles again, clamp a jumper cable on between the two vehicles, just to make sure they have a common ground, unless you're sure that you have a good ground path all the way from the light bar to the neg. side of the coach chassis battery. Even at that, the wiring could be too small somewhere and robbing power when you load it up like that. What size is the wiring between the coach receptacle and the light bar, including the umbilical cord?
