Drove about four hundred miles yesterday and arrived at my folks house with no headlights in my 86 6.2. K5. Is that a fuse (30 amp?) or a fuseable link? Memory says fuse but I could not find a blown one, what do yall say?

The parking lights are fused with the dash lights. Headlights are strait wired to dash power if I remember correct. That's why some people are doing circuit breaker fix to have brighter headlights. It will isolate power from the rest if the truck.might try and make sure headlight harness is plugged in all the way.the headlights go through the firewall plug as well so check that's harness as well

Are they protected by a fuse? Is it a metal heavy duty (can't tell if blown type) or a regular old tube fuse? It isn't a fusable link is it? I'm thinking no but it has been a while and I'm just grabbing chances to look between visiting.

Not sure if they may have a fuselink. They draw a ton if amps so I'm not sure that would last long. But chèck power at the switch and where it goes out from the switch to firewall.basicly check continuity from power input, then through the switch. Then if that checks out check wiring to firewall from switch and firewall plug to the headlight harness plug. My headlight switch went out and I still had parking lights do the switch could have died on you.

Most GM's had a curcuit breaker built into the headlamp switch for the headlamps,and no fuses or fusible links to them (73-87's at least)..its possible for that to fail and still have all the other lights work....I'd look around the radiator support for any dissconnected black ground wires ,one may have come off...there is another black wire for ground on the drivers side under the dash near the e-brake pedal that sometimes gets pulled off ,that might be the cause..
