Water Pump and Generator Problems

We just picked up our 2001 Fleetwood Bounder motorhome from a local dealer, where it had been since mid-December getting some body work done. It spent most of that time sitting outside the facility in very cold Erie, PA winter temperatures, sometimes well below zero degrees, waiting for a service bay to free up so our work could be done.

Despite repeated pleas over the course of the three months it was there to make sure the batteries were kept charged, both the engine battery and the coach batteries were dead when we picked it up.

We eventually jump started it and made the drive home, where we promptly plugged the coach into an electrical outlet to recharge the coach batteries.

We then discovered two problems that did not exist when we dropped off the motorhome with the dealer. First, we noticed the water pump was running and could not be turned off (this may have even contributed to the dead batteries.) The coach was winterized, so there was no water in the system to pump, but any attempts to shut the pump off at any of the switches was unsuccessful. We were finally able to turn it off by removing the DC fuse from the panel.

The second problem we encountered was the inability to turn on the Onan generator, either from the dash or from the switch at the generator itself. It clicks but does not start.

Before we return the rig to the dealer to address these problems, I thought I would check with you forum readers to see if there was some simple thing we weren't doing that could correct these two issues.

Any ideas would surely be appreciated.
  • You have a Intellitec controller that controls your water pump. This has been standard on Fleetwood products for years. Not all RV manufactures use this device. There are 3 momentary switches that signal the controller. If one of the 3 switches is stuck in the closed position, it could create the problem you are encountering. Check each switch to see that it is normally open. If all the switches are open then the controller is the problem.

  • Every fall as part of my winterizing I pull the 12V lead off the water pump itself, I also unplug the electric feed to the water heater and pull the plugs off the circuit board outside on the water heater. When I reattach the plugs in the spring I give everything I can a shot of "CRC Power Lube". This serves 2 functions as something cannot be left on by mistake and it gives the connection some exercise to help keep the connections clean.
    The "CRC Power Lube" is a excellent product as it is "safe for most plastics" and it "improves electrical properties".
    I have no stock in the company, I just recommend it as it is a great product! There are others that might even be better, I've used and recommend Corrosion X but it's a little pricey and I tend to soak everything down with it, using a lot! I find the CRC product to be just as effective.

    Anyway, your water pump should turn off with the switch (bathroom and/or kitchen). As said the controller only shuts the pump off if and when it builds water pressure. Most likely your controller is fine.
    The switches are usually direct wired with the pump and the fuse feeds the switches.
    I could be wrong and there could be a relay in there but I haven't seen one.
    I would have to see it and start by following the wires testing for voltage along the way.
    It is a 12V system so it's pretty easy and safe to work with. About all you need is a 12V test light/probe and some test wires with clips.
    Good Luck!
  • The OP said there was no water in the tank and the pump was running, which to me would be normal. The system must pressurize to shut off. It can't pressurize if there is no water in the tank. This is the way mine works, yours may be different but most that I have seen works on a pressure switch. JMO
  • Thank you, davebrown, for the advice on the water pump and the generator. After some charging time for the battery, the generator now starts.

    Would you know if replacing a controller for a water pump is a do-it-yourself project or better left to a professional?

    if the pump runs continuously the controller is most likely shot(about $40)and if the gen set clicks but does not turn over either u have poor battery connection,bad starter or batterys not fully charged or a bad battery/ies
