look it up, not kidding. over 14.0 the alt is over charging, i had 2 bad alts in a row, all charged over 14.0 and the info center said charging failure. they all tested good at the store too on that crap tester they use. but the volt meter dont lie. this was in my gmc pick up, but the same end result here.
I'll have to check with a DMM when It says it going over 14v again make sure the DIC is not wrong.
