We are presently on the road, Columbia Missouri. My water pump switch would not activate the water pump.Two days later turned pump on and it worked.
Now quit working again, when i hit one of the three switches, the light comes on and goes out when I release switch.

Please help.

We have the same problem. I've replaced the pump, all switches and the intellitec latching relay. The system can work fine for a long time and then all of a sudden the switches go out and the pump stops.

From researching on here, it's a fairly common problem with a multiple switching system. It's apparently a grounding issue. I have yet to be able to fix the issue. I simply just bypass the switches by taking the load and ground leads off the latching relay and connect them together with a 10 amp blade fuse.

Thanks for your help, I didn't have wifi until today. I will use your fix when I get home, for now i spliced a pigtail into the waterpump ground. I ran to the door attachment for ground, installed a 12 volt switch and it worked. When activated the lights come on for all 3 switches. A quick fix if you are on the road. I thought this may help others.

Your pigtail temp fix is basically the same thing, perhaps better as you have a quick on and off switch.

If you find a permanent fix for the problem, please let me know.

An RV tech told me that running new wiring from the pump with a single switch mounted to a convenient spot in the coach is the easiest way to fix the problem. The downside is then we would only have one switch as opposed to the current 5 switches. He said somewhere in the multi-switch system it's grounding out and turning off the switches.
