Hi,
On my '75 Wing, I have lo-beam, but no high-beam headlight. I cleaned the switch with contact cleaner, installed a new headlight, but still nothing. The white indicator light wavers a lot, and gets brighter when I rev the engine...
I have no idea when it comes to electrics, so any help would be greatly appreciated.
Thanks!

It's possibly your dimmer switch, even though you have cleaned it. You are going to have to track this down either with a voltmeter or a test light.
The blue/white wire coming into your switch is 12 volts coming from the RESERVE LIGHTING UNIT. The fact that you have lo beam, leads me to believe that you do not have a problem with your reserve lighting unit. If you have 12 volts on the blue/white wire then it is okay. Coming out of the switch are a white wire (which is your low beam)and a blue wire (which is your high beam). (You didn't mention whether your high beam indicator light was working or not??) Switch to high beam and check the output of the dimmer switch's blue wire. If you don't have 12 volts, then it's a pretty good bet your dimmer switch has had it.
