Default Headlights are dead !

Hooked up the headlights and no Light is coming out ! If the Headlight motors work is it on the same circuit as the headlights ? If so I have a loose connection some where ! Looked at the wiring diagram and it looks to me that they are on the same circuit ! Thanks In advance for the help !

I would start testing from the headlights back. I know...sounds too simple! Dennis

Are the bulbs any good. Check with a 12 volt tester at the connectors and work your way back.

You probably already know this, but just in case I thought I'd mention that the headlights are on a separate switch from the motors and will not come on automatically when the buckets are rolled up.

You can check the voltage at the connector just where the wiring comes through the inner fender at each front corner. I had quite a bit if corrosion. A little cleaning later and I had 12v again. You can also check the dimmer switch for corrosion.

Yes....I lost my headlights at night at Sebring in the SVRA enduro. Very traumatic!!! My dimmer switch burned up! So... please do check out everything an an orderly manner. 50 year old cars have unreliable parts.

I'm going with the dimmer switch. Easy/cheap to replace in any case.

Which is a good argument for putting in headlight electrical relays.

It could also be the dash switch. There is a thermal breaker in there that will 'strobe' the lights to get you home in the dark if an over current condition occurs; those can burn up. The voltage checks described above will isolate the problem.

It was the dimmer switch after all !!!! This is a great place to find tips on where to start ! Thanks to all !
