high beams?

[kiznook]

so my high beams dont work, 72 510, pull the switch and the relay clicks and the lights go out. Any ideas before I go through all the wires? bulbs are good, fuses are good (90% sure)

 

anyone?

easy step: hit the relay with a FH. sometimes they will click but not fully engage, esp when the contacts are dirty.

 

also check all the connections. look for broken / loose wires too.

 

were they working before this?

[kiznook]

yeah, they worked before. I think that they haven't worked since i parked it to do the motor. I don't really remember. tapping the relay didn't do anything...crap.

[71-521]

are you getting power out of the relay?

do the bulbs have power going to them?

I have had both high beam bulbs blow out at the same time for some strange reason in my truck...never did figure out why they blew...just replaced them and the new ones have lasted 5+ years so far...

There is only one way to check resistance/continuity, voltage, etc - with a multi meter. Trace the circuit with a meter and you will most likely find the problem - in a few minutes.

remember the lights on a 510 already are hooked up to the =side of the battery.

So if you take a TEST light which you should have by now put the alligater clip to ground and the TEST light pointer to each side of the high beam connectoe in back. Both side the light should come ON.

 

Now trup the Highbeam swithc and one side should go to ground.Meaning you TEST light should go out. IF NOT your not getting your ground. Ck back /ohm out/ ohm relay ect.

If the LIGHT does go out it is getting a ground and you have a bad lamp or just OHM out aross that (remove the connector)

 

Ck fuse box connections(winging this one here) if Low works I assume its good

There's also a ground connection in the Dside front corner. I think it has two black wires going to it. If it's not making good contact, you won't get your high beams. We just found this out doing Big Dave's wiring last week. He had some low beams, but didn't have high or running lights until that ground was connected good.

 

If the bulbs aren't burned out, then I'd be looking at the relay contacts.
