Duster Headlights not working even with power?
I tried to run a jumper from the light green wire to the battery
If you mean that you jumpered battery positive into that light green wire at the dimmer, and nothing happened then;
either the dimmer is bad
or the bulkhead is not connecting.
orrrrrrrrrrr like said; ground. Cuz you didn't say you took the grounds apart and cleaned them; but only said they "looked good." There are three or four grounds between the headlamp socket and the battery, and "looking good" means nothing, when it comes to electrical..
And I just gotta mention that when the headlamp switch goes, it often takes the fusible link with it.... which may or may not kill the ignition, depending on how badly the link melts. Take the ends of the link, one in each hand and try to give it a stretch. If it stretches obviously it's cooked. But just because it doesn't stretch, doesn't mean it's ok. IIRC the F-link is 7 strands. So even if just one of them is still good, then it will pass the voltage test. But the remaining strand may only support ignition.This is handy to know late at night when you smell melting plastic; just kill the headlights and pray you got at least one good strand left. If the engine stays running, carry on without the headlights.
But if you mean you jumpered the battery Negative to the lightgreen at the dimmer, and you didn't melt the jumper or see sparks,then the break is upstream from the dimmer, and now probably worse.
