Hi guys,what would make a alternator stop charging in a instant?.Here's what happened.Last Saturday starter just clicked.Found loose negative terminal,tightened,volt gauge went to 13.9/14 volts. Next day did a check of both batteries and terminals.Started boat up,checked voltage while running ,close to 14 volts on each battery.Out on the boat this afternoon and gauge on boat reads about 11volts or so.Started well all afternoon.
Arrived at home ,fired it up,check voltage with my meter,only 12.3 volts while running and boat gauge reading slightly lower than that.
Belt is tight,no noise.Wandering if there is a fuse or reset for the alternator. Hard to believe from point A to B on trailer, alternator just stopped charging.Any help or ideas would be really appreciated.
