The alternator utilizes a gas engine as its source of energy so it can send the power to the electrical system. If you want to learn more about the alternator, then let the experts at Midway Chrysler Dodge Jeep Ram tell you everything about them below.

Failing Alternator vs. Battery

It isn’t so uncommon that drivers will think that their alternator is failing when really it’s their battery. How do you tell the difference between the two? I the vehicle is unable to start and needs a jump, then try and jump-start it then immediately remove the cables after it has started. If the vehicle dies immediately, then the issue is likely a malfunctioning alternator. Otherwise, the car would be able to remain on.
