High Beams turn the lights off - 1990 200

[Vittorio Bares]

Thanks all.
 
It does turn out to be the switch - reaching in w/a small screwdriver I was able to operate the hi/low beam by moving the contacts. In high beam position, a small movement would turn on the lights.
 
So...how much should I expect to pay for the switch (used)? Or is it best to just go with new?
 
And yes, I did have higher powered bulbs (doh) - so, I'll be relaying once I get the switch - as well as adding aux lighting that I think I'll splice into the current headlight set.

Huw is right on the colors of the headlight leads. And, in case you hadn't
figured it out, brown is ground. As for contact cleaners, try DeOxit. I believe
the red is for mixed metals, since we don't know what's exactly inside the 
switch.

	As I recall, yellow is low, white is high. 
	
	And, yes, I'd suspect the switch.  Try cleaning it (squirt some "stuff"
	into it and operate it a few times.  Don't use "stuff" that attacks
	plastic, of course).
