The two components that keep the car running are the alternator and the battery. It is a shared power system, the battery starts up the car, the alternator then charges the battery, and the battery keeps on the power for the internals of the car. If one of them fails, the car starts to malfunction.
So how do you tell when the alternator is faulty? Or is it the battery? There are a few clear signs for each of their problems.
Signs Of A Bad Alternator
An alternator and a battery relays on each other. If one of them turns out dead, your car won’t work properly. So always keep them in check. Check your battery fluid levels. And pay close attention to the battery indicator in your dash for any sign of the alternator giving up.
