    Any suggestions where to start? I've swapped the bulb for a new one and it still doesn't come on, high or low. Gonna check the fusebox tonight and update if that's all it is

    Multimeter will help greatly. If it's not just a fuse.
    Negative on the engine and positive lead poking the connectors, type of thing.

    I've had a melted headlight connector, broken female spade connectors, corroded through wires at connectors.
    On and on. Multimeter and tugging on wires to see if they stretch as the copper is corroded away and it's only attached with the insulation, haha no seriously. Hopefully it's just a fuse,

    Okay after a look at a wiring diagram it seems my flasher cancel relay? Is missing. Which is very strange that the headlights don't work but everything else does, when the headlight relay is there and seems fine.

    I would guess that once you get a multi meter and start to trace the power going to the headlight, you will find the issue. Could be at the left bar switch? Sometimes the wires come off the factory solder pads. You will have to get some test equipment if you want to troubleshoot these issues.

    You don't need to spend a whole lot of money on a multimeter - for what you need, you don't need to spend more than $20 USD - not sure what that would be in Moose Bucks.

    Worth the investment.

    Got in there with a multimeter and did a continuity test. Found that the headlight plug goes to the *missing* flasher cancel relay, and everything else is there and seems to work fine. So that relay is in the mail now
