Ammeter to Voltmeter...who does it?

Mattax said

BTW. This probably one reason why charging systems got ammeters. A voltmeter can not reveal if current is flowing to the battery. It will show if the alternator is not working (voltage will be battery voltage 12ish) or can't keep up with demand (between 12 and 14). But when showing 14 volts, we can only assume the battery is charging properly.

And it would make perfect sense to keep the ammeter but for one thing....since it is a motorhome, I do want to upgrade the alternator. There were four alternators available on the B-Vans, 41 Amp. (Red Tag), 50 Amp. (Green Tag) and two different 60 Amp. (Blue & Natural Tags)....no idea what the difference is between the two 60 Amp. models. With the appliances that operate on 12V, the alternator needs to be powerful enough to keep the Coach/House battery charged, while driving. Everything I've read says that, if I upgrade to a 90A or higher alternator, I'm probably going to fry the bulkhead connectors and the ammeter, as it is currently configured. This is why I want to reconfigure the electrical system and go to a voltmeter.
