Technical Main Beam

[mower]

Can anyone help - all my lights used to work ok until recently. Now when I push the lever for main beam, my offside headlight goes out but nearside is ok. When on dipped, both are fine. I have spotlights wired into nearside main beam wire and nthey have been working ok for months, coming on only with main beam.
I have checked bulbs, they are ok and even swapped offside for nearside but still no joy.
I have cleaned up earth stations in engine bay but no joy.

Any advise greatly appreciated
John

I would have said its the earths but if they have been cleaned up then im not sure.

There Is a coil of wire. either on the driver side turret mount if the car is non injection, if it is injection then it is mounted on the slam panel next to the bonnet catch.

Make sure all the connection on here are clean and the coil itself is in good condition. this controls the main/dipped beam. Other members may know more than me.

Sounds like your not getting a power feed to the offside main beam. Checked the fuse as it's individually fused

Not sure on that one Jon. He said the whole light goes out. would it not keep dipped beam on?

Thank you all for your thoughts - I forgot to say that I have checked all fuses and all ok.
I had a thought that I could run a feed from nearside to offside, fused just in case, and that by doing this my problems would be solved.

Crazy idea??!!!

This rings a bell for me...
I had a dodgy bulb on the CLX - took me ages to suss it... bulb worked fine but would go off at times - I'd check it out - all seemed okay but would find fuse blown. In the end I realised that it must be the bulb. On closer inspection it appeared that the beam deflector plate was bending when hot and causing a short within the bulb. Worth checking, as if you just replace the fuse it's not long before it goes again!
No one else had this before?

 

[lightweightmick]

...you beat me to it there...
another problem I've had is the contacts being cooked - have you tried wiggling the 3 way contacts?
With fuse being okay you need to check you got power to that connector next - if you got power start looking at earth - it may not earth where you think btw on my 4x4 when light went out so did heater fan!

If your spotties are wired into the harness for your main beams - and your spotties are working - then it only really leaves the problem at the end of the line which are your bulbs.

Pop them out and check the connectors and fiilaments.

Thanks for all your replies - the spots do not come on when I pull the lever for main beam - I will recheck the nfuse again.

Nope, dipped goes off when main beam is switched on. Stops the bulb overheating as its twin filament.

Dipped does stay on if you pull the leaver to flash though.

Next time your out with mainbeam 'on', pull the stalk also, you'll see them get slightly brighter when dipped beam is re-instated temporeroly (sp?)

Not a good idea John, you need to wire back to the relay, if you piggy back off the working light, that section of cable will be handling twice the design current.

Thanks MIke - I'll leave well alone!
