Lotus Elan and Lotus Elan Plus 2 Forums

I was very happy with myself when I managed to change intrument bulb for the engine temperature gauge. I had some overheating problems before, and I now don't have to use the light from my mobile phone in order to check motor temperature while driving in the dark. (1974 Elan +2 130)

I also changed the clock bulb, but I found out that there is a gremlin in the wiring. The clock is now illuminated when lights are off, independent of the panel illumination switch, and turns dark when I switch on the panel illumination. Is this a standard feature, or is it an alternative wiring? The clock is of a german make, Hientze or something like that, is it the original clock (it does not work)

How do I get the clock light to work in correlation with the other instrument illumination/the panel switch? Can this have something to do with clock failure?

Sounds to me like you have an earth problem...not unknown...try a temporary direct earth to the clock lamp earth terminal.

Hi i have the same make of clock as you,i recently had it repaired and has worked well since.Not sure if its original,but i do know a lot of our cars have them in.

Probably no need for the illumination if it doesn't work...
Mine doesn't work either (or should that be 'ether'? ), but the illumination does...
I remember reading that it is worth taking apart & cleaning (how complicated can it be? - famous last words... )before sending it off for professional repair, but I have yet to try myself.

I took mine apart,lots of bits in there...the guy that fixed it charged 10 pounds,a small electrode had burnt out,which he says is common,caused by being fed too low a current,from a flatish battery...
