Had headlights, then high beam only, now nothing

Don't trust hi current stuff with an ohmeter. Under load, the contacts can fail

Just trace it out, you have a diagram?

Functional path is from HL switch to dimmer, out the dimmer on low and high beam wires, through the bulkhead, and to the headlights, which are grounded through a common ground. So check that

Backtrack with your meter/ test lamp. Figure out where the HL are in the bulkhead connector, see if you have power there, backtrack to the dimmer

I have a wiring diagram, but it's hard to tell much, as it could stand to be enlarged some, so I can better tell what is what, on this one. But, it is the best I have, would you, by chance, have a more simplified diagram ? Also, I need to know where the headlight relay is, on this one? Gotta go set up my light, it is way past dark thirty here in Arkansas. I appreciate the info that you have offered. I figured, as late as it is, nobody would be on here. All input greatly appreciated
