new head lights driving me mad

I have bought all new lights for me 1986 defender. I have a slight problem with the light I have side lights working and main head lights/dim beam. But when I push the the Indicator switch to the bulk head the full beam comes on and stays on as it should but if I pull to towards me to flash. It doesn't work and no bright blue light come up on dash could anyone tell me if I have wired some think up wrong. I have tryed to search but I couldn't find anything. Any help would be much appreciated

does the horn work?? IIRC the "flash" shared the same fuse as the horn, as its permananty live rather than the feed via the headlights
or
you had the cowl on the column off recently? the connections to the hi/lo/flash are on pins which may have come off.

Not had any experience with the headlight stalk but have installed extra lights running with relays. In my mind the terminals for full and flash both go to the same terminal on the relay so it could be the flash wire not all too smart.

Could try swapping round the full and flash wires round to see if that swaps the issue round the other way on the stalk, I would wait for backup on this is case I'm completely wrong and you en up buggering it. :-D

Hi thanks for the reply. I dosent have a horn at the moment its due anytime in the post. Could that have anything to do with it not working ? Although when I 1st wired it up it worked once the flash but now it doesn't work. Could it be the stalk/switch that could be dogey. I have pushed all wires back on made sure all fuses are all good I just dont no what else it could be

Swap the flash/full wires round, if this swaps the problem round then it's the stalk.

Ok cheers mate I will have ago with that tomorrow and get back with the results ;

I had this problem on mine. I had to clean the flash switch contacts every 6 months with fine wet or dry paper.
I've put a relay on it now and so far so good.

also to test without a horn, put your tongue across the wires that plug into the horn and ask a mate to honk it.

I have swaped the wires around and still works the same full beam works but no flash.

Guess we've figured its not the stalk then, if no one else has any guesses on what's wrong for a while I'll have a look on mine when I get home and had a few more guesses.

so the flash works, but full beam doesn't?

No flash still doesn't work now I have swaped the wires round still working the same full beam working and flash wont flash.

Slightly dodgy method to this one but it usually works quite well for diagnosis.

Get a length of wire and strip a few inches off each end then in this instance you could wrap/twist one end round the flash terminal at the stalk end and then wrap/twist the other end to the corresponding relay terminal.

It's obviously a faulty switch then

For sake of £20ish I might as well just buy a new switch to rule it out and see if I get anywhere with it.

Might aswell I guess, ooooo shiny new parts time

Check that your headlamp relay is working and wired up the right way.

Fuses 22, 23, 24 and 24 for your headlights and fuse15 for the relay

The flash uses a different circuit.

I had a similar problem but slightly different, when I put the lights on high beam they would not come off high beam when returning to main beam, changed the stalk as thought it was faulty, no difference, looked at earthing, all seemed ok. It was driving me mad and making no sense. I ended up getting an auto electrician in, he diagnosed it as a break in one of the wires close to the headlamp, replaced wire and it was sorted.
