So I have fitted the Mig clock now. It was highly reliable when indoors, but now that it is in the car, it is prone to stop while the car is cold. This is probably due to the temperature change, its location is just ahead of the heater as per Steve T, and it works well when warm. (hot, actually). I have a pal who works in oil additives and says his company used to supply lubricants for such things and recognised the problem.
So, has anyone connected the heater unit? I am presuming 12v supply will work ok, the heater unit was probably rated for high altitude so 27v not needed.
Btw, Steve, that's a lovely installation, mine is a bit more basic, but it'll be a nice project to improve it when I get time.
