Mine has been charging that high for 2 years no problem. Elimanate your factory ammeter and get a voltmeter. Too many classic Mopars have gone up in flames because of the factory ammeter, get rid of it you will be better off

Really haven't seen any evidence of that.
Seen a some problem ammeters. Seen some people blame ammeters when they did things like bypass the fusible link. Had some FS jeepers strand themselves when tried to follow an internet 'improved' ammeter delete.

And this has nothing to do with the meter showing higher voltage.
