My 1990 Winnebago Warrior as a rocker switch on the dash that rocks left, middle, right.
To the left is a charging position. It will stay in that position when put in that position. In that position, if the engine is providing charge it will charge the house battery. In that position it will NOT, however, let the house battery slave to the chassis battery. In other words, it only allows juice to go INTO the house battery, not out of it.
However, to the right is momentary, and as long as you hold it down to the right it will gang the house battery to the engine battery so that you can start the vehicle off of the house battery if the chassis battery is dead.
In the center the house battery is isolated.
I have to be careful because if you leave it in charge mode and run the generator you will damage the vehicle and/or generator voltage regulator, which I have done.
