If you have a DVOM, test for voltage at the positive battery cable at the battery, not testing at the battery but at the cable, when the engine is running. Now check for power at the battery post with the engine running, should be the same. Next test the battery when the engine is not running, key off, yes, this time testing for voltage at the battery post and cable, should be the same. If all four test voltages are the same, you have a charging system problem. The test at the battery cable when the engine is running should be aprox 13.5 to 14 volts at the cable. One thing to keep in mind, corrosion at the + battery cable can prevent the battery from charging and that's why the test for the charge system when the engine is running is best at the cable not the battery. If you have different readings when the engine is running at the cable and battery post, (the battery test results are the same when running and when not running, but the battery test at the cable is 13.5 to 14 volts) it is probably a corrosion problem. Clean the corrosion between the + battery cable until the voltages are the same at the cable and battery post. This is not a thorough test for the battery condition as you are only checking volts, not amps.

The cheapest way is to just take it to any Autozone , or similar parts stores ! They have the equipment on hand , AND they check it for FREE ! They will be able to tell you if you have a bad battery or faulty alternator . Most of these places are honest and tell you what if anything you nedd to replace . I thought I had a bad alternator a while back . Took it in and tested it . The battery had a bad cell in it .

So no need to buy the fancy equipment . Hope that helps !
