I have had the dreaded headlight problem of lights coming up and on intermittantly when switch was activated. Then it switched to a long delay after switch was on till lights came up. Then it turned into lights come on but do not come up. The relay was replaced when the first problem started, but thah did nothing to resolve the issue. I let it sit for a long time. I just pulled the headlight motor and found this

Does anyone know what size that resistor is it is too fried to tell.

Have you done a resistance check on the device and if so whats the value?

Is it possibly a diode?

crackerfeet

To be honest with you Malcolm I do not know athe difference between a diode and a resistor therefore I was hoping someone could tell me what it was so I could buy a new one and solder it in.

It does look like a diode and it looks like there is another one behind it. Behind the reddish wire. What does that one have for identification?

Andre Hedrick

Diode will pass current in one direction only, and the resistor is bi-directional.
The diode is used on the pop-ups to as a hold when the running "parking lights" are on after you turn off the head lights.

This is a diode, imho.

Will need to look in the electrical parts of the manuals to verify.

Those are diodes. Take your whole asm to the local Radio shack and have the guy check the one that isn't burnt. Just about any generic diode rated for PIV = 20V and around 6 amps will do, bigger is better(no wisecracks). Have him mark the Anode and Cathode ends for you. Replace both, soldering the Anode to the wiring harness end, and the Cathode toward the motor leads. Hopefully there's no other damage in the motor area.

Or, send it to me, and I'll do it up for you.

Yes they are diodes...

1A diodes are fine for this - this is just the feedback to the relay coils (it does not drive the motor) - but why did it fry... maybe the relay or wiring?

Another vote for diodes. Something like Radio Shack #276-1102 should work fine, since it doesn't carry the full load. It's the two devices that look like arrows in the diagram below. The color band around the diode case goes on the end that the arrow is pointing toward. Another way to say that is, the banded end of the diodes in your case goes on the side *away* from the blue & brown wires.

I think it's probably a diode.

They look like diodes from the photo, check the good part for infor. I would replace both parts while you are there and make sure they are oriented correctly, diodes only go in one way.

crackerfeet

got fresh diodes today and will solder them in this evening and put'er back and test. Will post results. Thankyou to everyone that responded especially Doc for having the part number handy for me.

crackerfeet

sorry, That special thanks goes to Sharkskin for the part number.
Thankyou

cracker..........as noted above make sure the diodes are inserted in the correct direction............almost all diodes have a 'band' at one end; this is the negative side. hopefully you can tell from the originals.

crackerfeet

The diode was the solution. Lights work perfectly. The replacement part cost 34.5 cents, thanks to sharkskin's replacement part Radio Shack #276-1102.

Thanks for all of the advice.

SharkSkin

Cool! Gotta love those easy(and cheap) fixes!
