Hallo Fuffi.
I realise the watervalves can be defective even when they make the clicking sound when activated. But I try to fix the biggest problem first. In my opinion the elctrical behavior is way of.
No minus on pin3 can not close the watervalve. If the valve is leeking than for now that is a minor problem. Easy to fix when pin3 has the required minus when inbetween cold&hot.
Also pin2 is not correct because it's full minus whatever position the hot/cold wheel is on. So I try and find out first what's the cause of that. Maybe the resistor in the hot/cold is broke.
I'll measure the Ohm's as you pointed out. But first I go and drive for a while with the input to the valves clambed of. It might well be that the water does not cool down as quickly as I thought. Thanks for pointing that out to me.
Keep you posted.
Thanks Henk.
