Hmmmm, puzzled and hope someone can shed a little light?
The auxilary water circulating pump is not running, resulting in warm (ish) cabin temps! What I have found so far:
I have a spare pump and the fault is there with both, pretty much eliminating the pump.
Voltage checked at plug (unplugged from pump) > 12V, plug connector onto pump , it will not run, unplug and check voltage again, 0V ! At first I thought I was not getting a good connection as after fiddling around with the meter probes, >12V. However, I connected the plug to the pump and measured the voltage this way, 0V, meter still connected I unplugged the pump and after 4 or 5 seconds the voltage came back to > 12V ???
Any ideas? I'm now guessing the pump is not simply fixed 12V supply but there are other things, it's more like a current switch rather than voltage?
Thanks in advance for any input
