What is this switch for?

Anyone know what this switch is for?
it is on a 1981 Itasca Sunflyer
It is below the fridge to the left.

Also, when I have my RV not plugged in to shore power my pump doesn't work and my panel that has all the tank levels doesnt work? any ideas?

it appears to me to be a power switch, because of the red light next to the toggle switch. maybe water heater. on the other problem, i think you have a problem with the 12 vdc system. check the fuses if you haven't already or look for a poor ground. clean terminals on the battery if possible. hopefully someone will come by who may have better info. hope you are able to get it fixed.

If the switch has a red light to the left of a rocker switch and the light is marked reset. It is likely the water heater gas control switch. If it is like mine, the down position should turn on the light and the water heater should come on.

However, the water heater takes 12 volts to work so the light nor the heater will work if there is a problem with the 12 volt circuit.

You note that neither your pump nor control panels work unless you are on shore power. That is an indication you have a problem with your batteries. Either the batteries are dead or they are not connected. These items works when you have shore power because the inverter/charger is supplying power and the batteries are not needed.

If you have a volt meter check the voltage across the battery terminals. Less than 11 volts and the batteries are discharged, check the charging circuit. You can also use a 12 volt test light. They are inexpensive, but less accurate. You can get one at any auto parts store. Just touch the light across the battery. Bright light battery ok, dim light battery discharged.

That said, I would bet the battery terminals are corroded or there is a lose connection in the wires. I would disconnect all battery cables one at a time and clean both ends with a wire brush till they are shiny. Reconnect and your problem may just go away.

Hope this helps.

P.S Do not overlook the battery ground connection. The battery need both a positive connection and a ground connection to every appliance or the appliance will not function.
