If you find yourself wondering, how much is an alternator for a car, here is a quick rundown of the costs. Replacing an alternator can be fairly expensive. The total cost will depend on the vehicle you are driving, as well as if you choose a brand new, or a rebuilt alternator. If you can do the work yourself, a rebuilt alternator can cost as little as $80 for older vehicles. An alternator for a newer vehicle can run $150 to $200. If you need a professional to install your new alternator, budget between $300 and $500, depending on your car. High end sports and luxury cars will cost even more.What are the Main Components of an Alternator? here

Start by checking your battery first. In cold weather, it's very common to have a dead battery that just won't start. Check the battery gauge on the dashboard to make out if the battery is sending a charge even when you have switched off the car. If there is a dim flickering light, then it means that something is using up power from the battery. You can then proceed to check the connections you commonly use, like the automatic window openers, windshield wipers and the brake lights. Switch them all off and try the battery again. Clean off any corrosion and check to see whether the battery will charge up again. Then check the battery voltage with a voltmeter. It should read close to 12.6 volts when the car is off. Then turn on the engine again and check the battery. If the voltmeter reads between 14-15 volts then the battery is normal. But if the battery reads over 15 volts or less than 13 volts, then there might be a problem with the voltage regulator, the wiring or the alternator. If the battery just wont keep a charge even when you have turned off all accessories, then it's time to take a look at the other systems that work with the battery to run your car.

Second hand alternators are pretty easy to find. Visit a local junkyard or parts recycler and they should have a wide selection of alternators. Another good source is the want ads of your local newspaper. Car parts are normally listed in the automotive section of the want ads. Craigslist is another good source of car parts. People parting out vehicles often sell the parts online and if you know what you're looking for, bargains can be found. Auto parts stores often sell second hand or rebuilt car parts, including alternators. Doing a web search for used alternators will bring up a number of sites. It's a good idea to check reviews of any sites before ordering, because there can be some shifty operators out there.What Do I Use for Checking a Car's Alternator Output?

Continue to run the vehicle at approximately 1,500 RPM and signal your helper to begin turning on the vehicle's electrical accessories, such as headlights, radio and cigarette lighter. Keep an eye on the ammeter. When the ammeter reaches 75 percent of the alternator's total rated output (most passenger vehicles have alternators that put out between 50 and 70 amps), signal your helper to stop turning on accessories.

Connect the 12-volt digital voltmeter to the positive and negative terminals on the alternator. The terminals should be marked with plus and minus signs, representing positive and negative. Also, the color red corresponds with positive, while black represents negative. here

Be sure that you keep the ammeter at least 6 inches away from the alternator in order to reduce the risk of interference. You should also ensure that your testing instruments are away from any moving engine parts, such as belts or fans. The vehicle must be started in order to conduct the load test. [links]

Signal your assistant to turn off all electrical accessories and then start the vehicle. Have him rev the engine to approximately 1,500 RPM. Look at your voltmeter. You should see a reading of approximately 13.8 to 14.4 volts. A reading below 13.8 is indicative of a faulty alternator. [links]
