I'm having two issues which may or may not be related. My unit is a 2006 Safari 25 with an 55-AQUAJET AES water pump.
Issue #1 is that sometimes when I turn the pump on when we pull in for the day, the pump will not stop running, even though the tank is full. If I turn off the pump power switch and immediately turn it back on, the pump does not come back on until water is run at which time it runs long enough to rebuild pressure and then turns off as it should. Is there a limit switch which might be failing and if so, is it in the pump? Or elsewhere?
Issue #2 is that with increasing frequency, the 12 volt
systems will die completely when water is running enough to activate the pump. If we're connected to shore power, the 110 systems are not affected. The lights, the pump and any other 12 volt
accessories will go out for 2-3 seconds but then they'll come back on. No fuses have ever blown. My assumption is that the pump motor is shorting out and I need to replace the pump but I don't want to replace it if there are other possibilities I need to check. Is the best first step to put my ammeter in line with the pump circuit and then just watch it while I run the pump and see if it decides to misbehave while I'm watching?
Any guidance will be greatly appreciated. Thank you.
