Headlight DRAMA!!
Headlight DRAMA!!
my headlights don't work!
all three wires to the bulb are showing up with positive in them.
i test the bulbs independently and the bulbs still work high
and low beam. what could be the drama?
and my indicator/cop flasher no longer operates the headlights?
Cheers

Here is a very rough sketch of how your lights are wired

Have you got 12v at all light terminals when the both globes are in? or when they are out?
I think the problem is in-between the globes and the switch, or the switch and ground

Check the "earths" - connections to the body.

You not said which one you have this trouble with , I can understand forgetting in your panic 
These buggers MY and L seem to switch the earth for the lights so bulbs wire end likely to have power all the time, but no earth. I recall them switchng both power pos and earth?
So confuse the confusion outta you if used to normal hook up. Pull headlight and turn combo switch out and tinker with it. I think if the high beam circuit is unhappy it won't power up or earth up low beam circuit. Check fuses, relays (little round aluminum canned ones above fuse panel (requiring neck craning) and the earths anywhere and everywhere. Were you doing somethng before with electrical or lights that may have helped this event?

One question, do your lights come on when you pull the combi-switch to 'flash' your headlights?
Here are some diagrams i have dug up.

Now if you turn the ignition on, and disconnect plug i90, on the car side, you should have 12v at terminals C and D. This means the wiring from the headlights is intact. Plug it back in.


Now unplug i86 and on the car side you should have 12v on pin 4.

Post your results and we'll go from there
