I agree, great info. I bought the Noco Genius 7200 charger, it was rated high on the AGM charger list. I need to let it do its full charge deal for a few hours though.

My alternator is a Tuff Stuff chrome 100amp Chrysler unit. I took it to Automotive Electric in my area, they rebuild Alternators.
He looked at it and said no way that design will put out 100 amps, he put it on his test machine and it put out 70amps like he predicted. I'm running an electric water pump and twin electric fans that don't kick on very often.
But yea, the whole battery/charging system seems weak to me.
My Duster was always at 14volts with a cheap parts store battery and cheap denso 60 or 70 Amp alternator.
