winking head lights

[dsteppers]

Bit of an odd one, but when i put my head lights on, the n/s rises then drops, then the offside comes up then the n/s comes up again. It also does this when flashing, the car not me. Any help is really needed, i'm thinking bad earth or poorly relay,

cheers for any help steppers

Hi there..

This is an old chestnut but the best approach should be:

• lift the car at the front put on axle stands

• Disconnect battery

• Lift the lights by winding them up by hand using the motor screws from underneath

• Check carefully and clean all connections/ joints each side for the lights, most of these can be done from underneath but you can remove each headlight and remove from the pod and work through the hole.

• Recheck operation by connecting the battery

If no change then check the lift control diodes usually on the fuse panel. Some early cars may have 2 remember the orientation of the stripe on the diodes. Check with a decent meter that voltage flows one way and not the other through the diode or diodes.
If not then replace with cheap replacement from Maplin or similar

If no change or improvement then let us know for more in depth surgery!!

Yeah, and check all the connectors too, they can corrode and produce all sorts of weird effects.
I think a dodgy earth, (my favourite...) because the description indicates stray voltages making the relays drop out ??

Check the whole thing - yeah sorry, you have to take the headlights out to get at the connectors behind them, and check main earth returns too.

My early 280 has one (a long 6mm bolt and lots of eyelets) by the fuse box

Faulty relay you can probably hear it clicking,had the same problem on my old wedge

When I switch mine off they go down then the drivers side comes up and goes down again.

Its a TVR it does strange things, so why fix it,

cheers for all the advice,

sounds like a job for a long dry weekend, maybe waiting a long time to do this job then,


thanks again steppers.
