Water Pump Lite

[jastinjr]

Have 2003 Allegro Bus. I have switch for water pump in the toilet room and bathroom, both had burned out bulbs which I replaced, but I now have a low dim light showing. You turn on pump the lights are bright, shut off pump and light goes out, but then they start showing a low dim light? and the funny part is when I added water to toilet the light went out and then back to dim light when I stopped added water, pump never came on. Anyone have idea of what going on?

If the problem started when you fixed the lights then that’s where you need to start. Sounds like a feed back issue. Usually due to a bad ground or shorted wire.
Tiffin also used a latching switch that was usually located lying on top of the fresh water tank. This also could be your problem.
