Same switch but poorly described. In running some tests, I think I have answered my own question.
It is a horizontally mounted "switch" with "Aux Battery" engraved above it. The switch is labeled "On" to the left side and "Off" to the right. The switch does not stay in the position it is pushed but rather returns to a neutral position. When I am plugged in to an RV park. the indicator light is on no matter which position the switch is in but when I unplug from the RV park and push it to the "Off" side, the indicator light goes off, the battery is disconnected and all lights and accessories go off in the RV.
What this is, is a battery cutoff switch. A previous poster gave me the idea of doing some tests with the RV unplugged and that did it. I have previously tested it only when I was plugged in and it did nothing. It could certainly be labeled a little better.
The start assist switch that Lew mentioned is located on the dash, under the steering wheel. I had to use this last winter when my truck battery went bad.
I did not want to get too deep into anything as we are parked on the Caribbean Sea near the Mexico - Belize border and there are no RV repair shops here. Or anywhere near here! Thanks everyone!
Sorry but I am not my mother's brightest child.
