Okay, what am I doing wrong??

How do the chassis batteries get charged while the coach is plugged into 50 amp service? Or, do they not get charged?

Went to start the bus for its once-a-month-because-I-like-the-sound-and- it-gets-things-lubricated start up and the batteries appear dead.

No cranking....nuthin'...

So, apparently I've misunderstood how they get charged while plugged in.

And, how do I get them charged now that they're down? It doesn't appear that the generator charges them, but I haven't let it run long enough to tell for sure.

Hey, Lew, if you push......... I'll steer...
