Alternators
It all starts with a few telltale problems: A dash light coming on for a brief moment, maybe dimmed headlights and a few flickering gauges. Perhaps there's even an odd smell, or a growling sound coming from under the hood.
Is this a case of automotive possession? No. Most likely it's one of many possible alternator problems, and without a little attention, this problem can cause car trouble ranging from slow starts all the way up to a dead car.
