When I turn on the headlights I get a red circuit failure fault. I have unplugged all the lights front and rear and no faults. I can plug in one headlight at a time and no fault but when I plug in both headlights I get the fault and all the lights go out. I have checked the fuses all good. I absolutely hate wiring so any ideas would be greatly appreciated!
