Water Pump Won't Stay Running
Posted 19 July 2012 - 12:08 PM
The water pump will not stay running when the water is on. If I wiggle the wires that plug into the pump it will come on when its calling for water. Once I think I have it fixed or try it later, the same thing happens. My question is do you think I have a bad connection or the pump is bad, or is there some kind of relay I need to check? The Water pump is a Shurflo 2088-403-144
Also, I turned on the water pump switch and removed both leads from the water pump and I was getting 13.75 volts, that tells me the switch is fine and power is getting to the pump. I also took some WD -40 and sprayed on the terminals to clean them and cleaned the pieces on the end of the wires. If I wiggle one of the wires and pulled up on it just a little, it goes to working, but soon as I go in the coach and cut the water off, then turn it back on it quits.
Is the end of the pump where the wires connect removable or replaceable?
Any help will be appreciated,

I looked at the pump current range for on load pressure to 50 psi. The pump draws between 3 and 4.5 amps. This should be well within most DC switches current range as well as the latching relays used on most RV's.
