Dim Headlights 200 1985

posted by  someone claiming to be sdewolfe on  Mon Nov 17 03:00 CST 2008 [RELATED]

Howdy,

It sounds like a resistive path to ground on power side of the headlight circuit. I would isolate first one headlight and then the other to see if I could change the symptoms.

Here are couple of links you will find handy while troubleshooting this problem. The first is a page showing Bosch/DIN numbering scheme for relays and switches and components. It will come in handy as you chase the 56 (headlights) and 56a (high beams) connections.

The second link has a wiring diagram for your car.
