I have aproblem with the display unit in that the time is not rtetained when teh engine is switched off.
I have obtained a replacement display unit and still the same so I suspect the car wiring.
I can measure all the voltages but I don't know which are right/wrong. I can see a combination of 12 V and 0 and even 6V on 1 pin (obviouly changes depending on key position - actually the time is only finally lost when the key is withdrawn.

So - I need to know what input voltages to teh unit to expect at various diffeent positions of teh ignition key - does anyone know where I can get this info?

Many thanks,
