Headlight switch wiring.

I think main beam comes in on blue via light switch relay and goes out on blue/white trace, flasher comes in on brown/purple trace direct from battery and goes out on blue/red trace. Ooo 4volts not good, please let us know when you've checked the supply.

I suppose the supply must be okay as the full beam works fine anyways. I will check anyway might even have a nosy in a minute seeing as I have lost all the bolts for the steering cowell anyway.

Battery voltage on the blue wire, 1.5v at the purple wire with the switch pulled.

As i said i think the blue is the feed for the main headlights goes out of the switch on blue with a white trace, i recall you said the lights were ok, just the flasher, if the high beam is on when you push down forward on the stalk it must be your switch as the supply on the brown and blue with red trace that go to the lights are all working all that changes is the way the switch operates.

Looks like it will be easier to just get a new switch :lol:

Just put my new switch on and still no flasher. The problem is the purple feed. That is what is only 1v. Might try and hook up a new feed from the battery and fuse it separately as oppose to finding the fault with the purple one?

What! Your joking! Dig out the purple wire and do it properly man! Its gone too far now its war!!!! I didnt think the purple wire supplied the headlights

Cant you pop it up to yorkshire and ill have look? Lol

Best regards

I don't think it supplies the headlights just the flasher I think. Its the only permanent live in all of them and goes onto the pin that makes contact with the switch.

The drive from Devon and Yorkshire in the time it would take the new switch will have broken. :lol:

Nothing actually stopping me making a new fused feed though is there.

Not sure if this has been said or not, but flasher operates on it's own circuit and doesn't share the same lines as dipped/main beam. It does share the same relay though. Ultimately, this means you can "flash" without having side lights or dipped lights on.

I will assume you've checked all fuses, maybe try changing your dim-dip relay, if it's old the "flash" terminals might be burnt out. If this doesn't fix, and your main beam functions when you push stalk away from yourself with dipped lights on......then it's a problem with the live either before or after the stalk, multimeter should confirm, alternatively use a length of wire to hotwire from the battery.

Thanks for the reply

Never even thought to check the relay will have a looksy. I assumed the flash had its own feed and just switxhed that onto the main beam. The purple wire which I belive feeds the flash is only at 1v. Blue wire (headlamp feed) is battery voltage. When I pull the flash switch 1v gets passed through to the main feed so my problem is with that feed I believe. If I cut the purple wire crimp a bullet connector to the purple straight from the battery and test that should hopefully work.

page 20 here is fairly useful...I am having a similar issue.
