Re: Headlights don't work and it's not the dimmer swich.
electric issues are a process of elimination and easy when you think methodically. Don't just buy a bunch of parts and throw it at the problem.
get a probe light tester and check for power at the socket. If you have power at the socket then fix ground issue.
if no power at socket then test backwards towards the power source, Ex. in and out of the switch.
if no power at switch test back to fuses and power supply.
eventually it will lead you to the problem.
