Welcome..... you have a lot to learn! This site is full of knowledge and information so use it wisely grasshoper and you learn much.


The Use / Store switch connects or disconnects the house batteries. When the shore power is plugged in, the red light will always be on in most cases... even if the switch is in the "Store" position (batteries disconnected).

If the Use/Store switch is in "Store," your batteries are disconnected and won't be charged by the converter when on shore power or using the generator.

If you unplug shore power, the light will be on in the "Use" position and the light will be off in the "Store" position. So unplug the shore and make sure the red light is on and then plug back in so you know the batteries are connected and charging.

There are other ways to know as well. If you have the FireFly or Rapid Camp multiplex display panel that has the house and chassis voltage, you will be able to tell when the switch is in the "Use" posiiton because your battery voltage will be over 13v when it is charging. If you flip it to the "Store" position, you will see the voltage drop as you disconnect them from the converter.

If you don't have the FireFly / Rapid Camp display panel with the voltage readings, you can use a voltmeter or install a permanent voltmeter so you always have a visiual indication.

There are also posts on here where people rewired the light at the relay so it is only lit when the switch is in the "Use" position.

After having several years of RV'ing under my belt now with a couple different coaches, this is a non-issue for me... but I agree it is a lousy design.
