Fred,
First off, I'm certainly no expert on vehicle/motorhome engine charging systems. And, I certainly don't doubt you know what you're doing when checking your own equipment. But, as long as I've been camping, starting with a couple of trucks and campers, then, two class Cs, a '78 Dodge "4-Star" (440 cu.in.), an '89 Ford Class C, (460 cu.in.), a '99 Fleetwood Bounder Class A with the V-10 and finally, our present coach, an '04 Itasca Horizon 36GD with the 330 C-7 CAT and, every one of those units have the engine alternator charge both sets of batteries.
I would think that Monaco, as advanced as I've been lead to believe, and or the chassis they used at that time, would have designed into the coach, the ability to charge the house batteries with the engine. I mean, if one really liked Monacos and, did a lot of dry camping, then moved around a bit, the only way one could charge the house batteries is by generator.
I'm just learning things here. I don't mean to beat a dead horse but, are you sure that you don't have something broke or, disconnected that is supposed to be charging your house batteries while driving? Sure seems a bit odd to me but, again, I'm no expert. Just wondering.
