Charging house batts while driving
So trying to help out a friend with an old 1990~1992(?) Fleetwood 34' Southwind and I'm not totally up on how MH stuff works. How do the house batteries get charged going down the road? There appear...

The relay that ties the 2 sets of batteries together, is only supposed to be used for starting. If the coach battery voltage goes low enough, that it won't start the engine, assuming the house batteries are in good shape, there is a button on the dash that will temporarily tie the two together, to help it start.
It is a momentary switch, and as soon as you let go of the button, the relay drops out and the 2 are separated again.
There is however, a black box near the batteries, (or should be) that the charging wire from the alternator goes into, and then it is split, so that both sets of batteries get charged at the same time, but will not backfeed into each other.
There is nothing to do, it is automatic.
