battery or alternator problem?
i was driving today and when i came to a stop i notice my voltage gauge was really low (around 10v) and when i accelerated it would go up to about 12v and progressively float around, could the battery not be holding a charge or is the alternator not giving a good enough charge??? please help

Good luck, and hope it is cheaper than an alternator!!

also...
this problem just occured today, the alt always charged at 14v.. now all of a sudden the voltage is dropping at stops & returns to normal during acceleration- the belt's tight & the the terminals are tight too & clean.. would this most likely be the alt b/c they're both original equip & i was planning on replacing the battery & alternator anyway
