    The headlights failed on my '79 K5. The problem turned out to be a broken wire at a splice near the starter terminal. I tracing out the wiring I did not see any Fuse protection. Does anyone know where it is located? I can splice a new piece of wire onto the leads, but first I would like to know if I am bypassing a fuseable link or if some other form of protection is used.

    I have not been able to find a electrical drawing for it. There is not a fuse in the box labeled headlights. The largest fuse is a 25 amp. There is two 30 amp circuit breakers. One is label A/C the other is marked ACC. I am going to look some more tonight to see if I can trace the wires out.

    If I remember right, the headlights are protected by the "ACC" breaker.

    I'll ohm it out to the broken wires to see if it is the right one. I tried to remove it last night but it didn't want to come out. Do these unplug like the fuses? Thanks for your help.

    They are supposed to pop out like a fuse, but are typically tighter - I usually give them a little persuasion with a pair of needlenoses.

    The headlight switch has a "thermal overload" built into it. It resets after cooling off.....if the current draw is back to normal
