A lot of auto part stores will test them for free. Give them a call. Your alternator can only be tested when the engine is running, therefore you will have to get a boost or use a battery charger for the battery. If you have a voltmeter, test at the battery terminals with engine still running, if you get 13.5 to 14.7 volts, the alternator is charging. In some cars, the voltage could go over 15 volts if the battery is close to dead (right after being boosted), but the voltage should go back to normal as the battery gets closer to fully charged. Turn off the engine, the voltage will go down to 12.5 volts if the battery is now charged, lower if is not. If there is no change, the alternator is not charging. KGP484
