hello everyone,
my headlight only work when I move the Twilight Sentinel all the way over. When I pull the headlight knob all the way out the only lights that come on are the parking lights. any idea why this is happening? I have a 94 FWB.
thanx

Could be a defective headlight switch. Since the lights all work on the sentinel circuit, that means the circuit itself is OK. If the switch is making contact for the parking lights but not the headlights, that could be it. You can either remove the headlight switch and replace it, or remove it and test it to see if it needs replacement. Disconnect the negative battery terminal beforehand, as headlight circuits are continuous!...
