Just installed a brand new alternator on my 1995 Tahoe, AC Delco 100 amp. It’s possible I didn’t notice with the old one, but the voltage meter does move slightly back and forth with the rhythm of the turn signal. Is this considered normal? The only other time I notice it dipping lower than 14 volts is when the rear defroster is on, that seems to suck the most power from it for some reason. Video attached. Some people may not even notice it. Thanks ahead of time!
