Alternator Repair in Phoenix

An alternator is no simple thing to repair or rebuild, so leave it to the experts at Johnston’s Automotive

Phoenix is one of the places on planet earth that you definitely do not want to get stranded with a dead car, especially in the hottest months of the year where the heat can legitimately be a danger.

Alternator replacement can actually save you quite a bit of cash, if you are able to catch the problems before the issue spirals out of control.

The main reason that the alternator is so important to your vehicle is because it is the component which allows your car battery to recharge while driving. Though this may seem like a small task, fully understanding the importance of it requires an understanding of the electrical charge that is required to actually start a car.

Once the vehicle is started, the alternator belt is actually driven by the engine and creates a current which charges the battery which each revolution.  Here are some of the most common side effects of alternator problems.

  • Rattling or spinning noise – If the alternator bearings are wearing out, a distinct rattling or spinning noise can sometimes be heard in the alternator.  If left unattended, you can damage the alternator belt and run the risk of other classic alternator related problems.
  • Accessory failure – Headlights, radio, dash lights and even the starter can be affected by a faulty alternator. This is usually one of the last warning signs you will get.
