Head lights dont work
« on: March 10, 2011, 02:10:20 pm »
The headlights dont work on my 83.
Where is the headlight relay and is there anything else I should look at to make the headlights work?
The head light harness looks pretty good no splices and the wiring doesnt look dry rotted .

it could be the switch itself.  To remove it, there is a button you have to depress by reaching up under your dash on the side of the switch--push the button in and the knob stem comes out from the front.  Then remove the switch and replace, or just remove and test by jumping the terminals with a stripped wire.  Unless your '83 has the steering column light switch, i don't know when they switched (pardon the pun) over to the steering column light switch.

It has the pull out style on the dash switch.
If it is not the switch where is the headlight relay?

Could be the high / low beam switch. Have you powered up the bulbs?
Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs

Just to let you know, there is no Relay in the Stock Headlight system.

There is a few people, myself included, that added relays to give full voltage to the headlights.

I made my own, and used 3 relays, to allow Low, High and Low and High to be on....
