Another thing to check on an alternator is that it is not overcharging either. With the voltmeter in place (say probing the cigarette lighter jack) make sure that when you rev the engine the charging voltage does not move a whole lot. As sysopt posted above it should stay somewhere in the high 13V range (maybe low 14V). If it swings wildly you have a bad regulator... which can also lead to damaged batteries.--JJB--
