Headlight issue, need help!
I am having an issue with the headlight on the passenger side of my 81.
The low beams for both sides work fine, no issue. When I put the high beams on, the right side goes out all together. I replaced the bulbs, and the problem continues. I check the wiring and don’t see anything off, and there is power going to that side because the low beam works, but goes out when I put the high beams on.
Any suggestions before I start tracing all the lines? The car is 100% original and has never had any wiring cut into.
Thanks!

Keep this in mind:
The TAN wire is your low beam.
The LIGHT GREEN wire is your high beam.
So...if you are not getting 12 volts on the LIGHT GREEN wire when you have your high beams on....you can have a bad dimmer switch or high/low beam switch that is mounted on the left side of your steering column..behind the vinyl trim panel that closes out your column to your dash.
IF you do have 12 volts on the light green wire when have have it disconnected....then also remember that you MUST and a good ground on the BLACK WIRE.
You can still have a bad/broken wire somewhere ..and this will take deductive reasoning to determine if you do have that issue. Such as ...you have 12 volts coming out of your dimmer switch connection...but no power at the headlight connector.
