1980 Toyota Corolla no headlights

Unread post by gale » Mon Jul 29, 2013 5:26 pm

Had no high lights, changed bulb and now no lights. Next problem, engine oil smell which is making me sick. Cleaned around the engine but still when idling worst smell. What can I do?

1980 is going a while back. First thing to check is voltage at the engine room fuse box for the two headlight fuses. they are powered up from the headlight relay in the same fuse box. Unplug the headlight bulbs and check for power at the wire harness connector. With the headlights in the low beam on you should have ground on the red and green wire. the red and yellow should be open and the last wire should be power from the fuse in the fuse box & relay. When you switch to high beams the red and yellow should be ground and the red and green open. (high beam won't have the red and green wire going to it) So, it looks like the headlight switch sends power to the relay, the relay powers up the two fuses then the fuses feed the headlights. the dimmer switch tells the circuit which one gets the ground connection. do you know how to check the circuits?
