Hi everyone

I've just got my sapphire back together and the headlights are doing something strange. If I put the sidelights on the dipped beam bulbs light up too but they're dim. If I put dipped beam on nothing changes. If I then try and switch main beam on nothing happens but I can flash the main beams.

So far I've tried a different switch and a different relay but nothing has made a difference so far.

What could I be missing here?

Thanks

 

Can anyone suggest anything before I take the dash back out again?

 

Hello, well problem to me sounds very much like an earthing fault. So these need to be checked for cleanlyness and security. Have you got a volt meter or can get hold of one, check that you are getting 12v at the right terminals at the right positions of the switch. Though the flash circuit being correct has thrown me, but that could be a red herring so preaty sure its an earth fault, happy fishing.

 

Thanks for the reply. I've checked the earths behind the dash around that area and they seem ok. Everything else works perfectly on the car except for the dipped beams and mains. With the ignition off just the sidelights come on as they should but with the ignition on the dipped beams come on but not as they should.

If I was to put a meter on the back of the main/dipped bulb what voltage should I see on what colour wire with the switch in what state? There are 3 wires going to each bulb, white, yellow and brown.

Thanks

 

Just put the dash back in and I was getting the correct voltage at the switch so I guess the fault is elsewhere. Where else should I look? Are there earths near the front lights?
