NE Indiana
The alternator on our 6400 went bad yesterday and was putting out way too many volts and boiled the batteries then the windshield wipers started going with the switch off. So we fixed the alternator and batteries and now everything works except the windshield wipers won’t shut off. What could be the problem.
