I have a 1993 hijet. I'm having trouble with the alternator not charging the battery. I have purchased a new alternator. With the new alternator put in the battery light on the dash lights up. Never did that before with the old alternator. Still not charging the battery with the new alternator. I have also added another ground wire from the battery to the motor. All the wiring seems fine. Needing help on trying to figure out why it's not charging.
