Signs of Alternator Trouble
A failing alternator doesn't always fail outright. It may send out subtle warning signs, such as flickering lights, a dimming dashboard, or difficulty starting the engine. Paying attention to these signs and having your alternator tested at the first sign of trouble can help prevent a catastrophic failure.
Lifespan of a Bad Alternator
