Fresh Water Pump Help

My fresh water pump is not coming on. The red indicator light on the panel is on showing me its ready to operate. My first thought was to check the pressure switch but I don't know where it is. On the red and black wire coming in I have no power. Any suggestions.

Thanks a lot

Hi Tom, First things first........Welcome here!
Based on your post, I would be looking for the 12VDC fuse location, Look around your water bay for the pump and the controller, maybe you will locate the power/fuse source. I am not sure if you have a controller in your system? See attached file. The other thing that might speed this up for you is, send a private message to one of the Moderator's and ask them to move your thread (question) to the "Entegra section" for better response's.
Here is the Moderator's list iRV2 Forums - Show Groups , and you will see next to "contact" a "send PM " button.

The pressure switch and the pump will not work if you don't have 12 VDC on the supply wires to the device.

Do you have an Intellitec Latching Water Pump Relay installed with your pump?

It looks like this.

If so then you need to check the integrity of the connections and whether you have power on the 12 VDC positive terminal.

This is a ground switching relay for the water pump.

Also check the in-line fuse for integrity.

It's likely the pump relay, as Dr4Film describes. When you flip the pump switch, it merely triggers the relay which in turn switches another 12v line on power to the pump (most often the relay switches the ground side rather than the hot).
