Its easy to check with a cheap voltmeter-first check batt voltage with car off-should be around 12 volts, take note of reading. Now start car and check voltage-should be higher. If so you are good. If no difference at all or less when you turn on accessories, , it's not charging. If batt voltage is low (10.5 or less) but goes up when running, your batt is on the way out.
