Second, and it's one that many people might not think of right off, is the emergency brake system. If the breakaway switch is shorted, you could be getting power from the coach battery.Lyle
I agree with you Lyle. Since the truck checks out (if I believe Ford), I'll investigate for shorting all the way from the battery terminals. Any opinion on the wiring zip-tied to the spring?
