How do I test my alternator?
I'm not sure if my alternator is charging my battery when truck is running. I'm not driving the truck yet just able to get it started and sit there idling. I have a multimeter tester. Is there some way to hook up my meter to tell if the alternator is actually charging when the truck is running?
