Tips on Alternator Repair

While the alternator is not entirely necessary, it is a helpful part to have in your car. The alternator acts as a generator that keeps a charge in your battery as well as provides electricity to the headlights and other items that need a charge. 

• The battery and the alternator belt should be tested before you decide to replace the alternator. 


• Before you start ripping parts out of your car, you should have the alternator tested to make sure that that is where your problem lies. Most all auto parts stores will test your alternator for free. If you don't have an auto parts store close by, you can purchase a voltmeter for approximately $15 to test your alternator yourself. 


• If you are not mechanically inclined, you should leave the alternator replacement to a mechanic. They will know how to properly remove and install the alternator so that it works the way it should.


• When replacing the alternator, you should also replace the hoses and belts whether they look like they have been damaged or not. They can stretch and become damaged on the inside in places that you cannot easily see. Replacing the alternator hoses and belts will also ensure that they don't wear out before they should. 


• If you are attempting to repair internal components of the alternator, be sure that you read the car repair manual thoroughly so that you know whether it is something that you can handle on your own. Repairing bushings, bearings and wiring inside the alternator can be complicated.
