Water Pump problems
Hi Folks! I need a little help with some water pump issues.
A couple of months ago we got our rig out of storage and found the water pump wasn't working. I have experience with the 'vapor lock' so I tried to manually prime the thing to no avail. The problem I noticed is that it wasn't pumping at all. The motor wasn't running. When I checked the screen filter attached to the pump, I fond a small piece of plastic in the basket. I checked all the fuses, found them all to be good and went on about my way assuming the pump was ready for replacement.
After receiving my replacement water pump, I performed many Cirque de Soliel contortions and got the pump swap done. When I turned on the power, the new pump wouldn't run either! DDDAAAANNNGGGGIIITTT!!!....
I checked fuses again. Everything else on the 12v panel works and all the fuses are good, so I kept checking.
In a moment of brilliance (although late in the game), I took the old pump to my truck and touched the wires to my battery. The old pump fired right up!
So now, I am trying to figure out how to trace the obvious power problem.
There are two switches for the pump, one outside and one inside. So here's what I"m thinking: a) maybe the switches are bad - both of them?, b) maybe the power wire from the back of the 12v panel lost connection?
Other than tracing the electrical line, I'm not sure what else to do.
To trace the line, I will empty the basement, then pull the thin wall material. That will expose the back of the 12v panel (I think) and should show me the entire run from the panel to the pump.
Am I remotely on the right track? Do you guys have any other ideas?
Thanks so much!
