Your voltage regulator should regulate the charging voltage to 13.8-14.2 volts. Anything less than that is too low. comp-spec 07-03-2009, 12:30 PM 13.9 is normal (give or take a couple) If your seeing 12.1 get your alternator check that's to low karrensharpie 07-04-2009, 06:18 AM You should be getting codes shouldn't you? johncoffey 07-04-2009, 06:56 AM Definetely too low.
