Clock illumination inverse

PostPost by: Uboat » Sat Aug 09, 2008 7:45 am

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.

Probably no need for the illumination if it doesn't work... :lol:
Mine doesn't work either (or should that be 'ether'? :wink: ), but the illumination does... :?
I remember reading that it is worth taking apart & cleaning (how complicated can it be? - famous last words... :oops: )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...
