Hi everyone, I have a problem with the internal water pump for my MH. For some reason my waterpump has stopped working, I replaced with a new one but still have the same problem, I checked that when one of the taps(micro switches) is turned on that I get 12volts at the wiring to the pump(wires are pink and brown) but the pump still doesn't work. The pump works off an external 12 volt supply but unfortunately not when I connect back up normally. Could it be a current issue? Any help would be much appreciated. Thanks
