Sean,

Check and clean the connections at the battery first, probably not the problem but always the first to check.

Remove the headlight switch by unscrewing the knob and bezel and let the switch hang down by the wires where you can see the terminals. Now is the time for some diagnostic work. Get a wiring diagram and a test light and confirm there is power where it’s supposed to be. One-at-a-time, remove each wire from the headlight switch and inspect and clean the terminals.

It is probable this is a corroded connection. It is possible this is a headlight switch failure or other. Only careful diagnostics will tell.

Best,
Grady
