Until 2 days ago my lights worked fine. Now i have no low beam, high beam and parkers work. Any suggestions? Thanks. ( its a 91 Sierra)

[Fatzook]

Blown fuse??

[maloo11]

Nope, checked that.

Globes??

Had one go and people didnt notice till the 2nd one has gone..

[Buddies72]

Last time that happened to me it was in the switch.

Buddies.

[maloo11]

Not globes either. Im thinking its the switch or something up in there not connecting properly......? Will have to pull it all out in next few days i think

[lump_a_charcoal]

Checked the other fuse?

[ajsr]

earths down near the headlight both sides screwed down tight?

Whip out the multimeter mate, I'd be checking all the cables and see if your getting any voltage running though the cable.

x2. best place to start IMO. instead of working out what isnt working, work out what is.

cmon guys you should all know this one by now

let me guess the high beam dash light lights up on low beam and its all gone strange?

4th fuse in from the left in the top row is blown, it will test ok in there though you need to pull it out and look at it

if its not that one its close to it, cant remember its exact location

What Royce said.

If its continually blowing then check your alternator wire is connected and good.

It was continually blowing for me and I found that my problem was that my alternator became disconnected from the loom and when I braked when the lights were on it would blow that fuse..

[maloo11]

Its not the fuses. Pulling the switch out today. Wheres the best place for replacement parts?

[Rusho]

Switch// Send want33's a PM

[maloo11]

im gettin power to all 3 wires in the light? This cant be right. Even when the light switch is off, im getting power. Has to be switch rite?

[royce]

they are negative switched, power there all the time and it witches the high or low beam filamnet

unplug both lights and try again, youll have power on one vertical pin only

did you pull the fuse out and test it by itself or not?

[atari4x4]

yours must be possessed by jebus.... suzuki's are negatively switched.

[maloo11]

ok. i unplugged both lights, have power to one virtical pin as you said. So why is low beam not working? Switch? Hi beam and parkers work fine.

[royce]

now with both plugs unplugged see if you have earth on the 2 horizontal pins ONLY

[maloo11]

thanks heaps for your help. Turned out to be a bad earth bad earth.

I had no low beam this morning, not the fuses, guess I gotta check the earths.
