Thanks for the reply. Good questions.
I cleaned one ground near the battery, though it didn't need it. There's no rust of any kind. The engine comparment is as clean as new. Little to no corrosion in the several connections I inspected. I did swap headlight bulbs, same problem (so its not the bulb). Voltage to the left bulb is also 6-7 volts. So I'm thinking it IS a relay thing and the voltage is being backwashed through the right headlight cuz when I uplug the right headlight bulb, the left side goes out. But where are these relays?
Our Superscrew Dealership "never heard of such a thing" (not according to my buddy who works on 'em). Didn't know whether one or two relays. "Bring it in". Sure hate to. I'll have to take out a second mortgage.
