I just had to have a brand new alternator and battery (best one sold - or at least most expensive - at Sears Auto which was the only shop open this weekend when car broke down). At night with lights on the battery ranges from 11.8 volts when at idle to 12.5 while driving. During the day the battery ranges from 12.2 volts to 13.1 volts. I’ve been told this is too low (especially the night voltage) with brand new alternator & battery. Could there be another problem?
