help with water pump wiring
My coach has two switches for the water pump. I had a old control panel 1989 from larson. This was bad so i am replacing is with a tech-edge unit. My question has to with the water pump switch setup. The system had no controller in the circuit that we can find. Now it the same wires are connected to the new switch in the same positions the main kitchen switch will turn on the pump nd the led on the switch will light. The old switch had no led on the switch but had a led board with wires running to that board. But if the switch in the bath is off the switch in the kitchen will not energize the pump. The bath switch will not energize the pump unless the kitchen switch is on. So the kitchen switch must be on and the bath switch must be on to run the pump. I also have a purple wire at the pump switch area that has 12 volts only when the pump has 12 volts.
Any held will appreciated
