I posted this in the wrong section b4 I need help. I have my headlamps going out then on again when they are out there is no power to the acc fuse I took a look and pull on the fuse links at the starter they seem ok. I think there is a ground on the wire at g5 in the c100 block. is there any places where these wires are known to be tight and short out? I pulled the harness a little to try and get the lights on but ng I thaught I may be able to narrow it down to a specific area that way HELP...:hail:

 

G5 is the hot wire that goes to the light switch, the ACC fuse, and the fog lamp relay. Here is a schematic of it for you.

 

Having the headlights go out and come back on repeatedly is usually caused by an overload in the circuit that trips the circuit breaker in the headlight switch itself.
Are you running any other lights using the headlight wires for power? Or have you recently upgraded your headlights to something that draws more current than stock (higher wattage)?

 

no, the only thing new is msd. lights, acc inst and tail went dead on the road last thursday nite. I think there is a high resistance short, the fuse link didnt burn up. stll lookin. thanks
