The BATTERY stores enough power to turn over your motor and makes you move. But that is about it, you can go a couple of miles on the battery. The ALTERNATOR produces enough power to run your motor. ALTERNATORS need to re-energize your battery. When the ALTERNATOR isn’t working there’s not enough power for everything to run. ALTERNATORS get exhausted. They are turned by the SERPENTINE BELT and spin 2 to 3 times faster than the ENGINE. If you are having issues getting the ALTERNATOR checked so you don’t get stranded.
