Over Charging
 
My 1995 Volvo 850 died in stop & go traffic. All warning lights came on, radio faded. Jump started, then battery was weak. We charged the battery off and on for a couple of days, car ran OK but warning lights stayed on. Warning lights went out, but battery continued to be weak, and we continued to charge off and on for a couple more days. Then the battery exploded. We replaced the battery with a new one 2 days ago; today the battery is over-charged; registering over 16.5. Could this be an alternator problem, voltage regulator, or what?

Yes, yes, and possibly. :confused:

If you're not comfortable diagnosing auto charging systems then get it ckd out by someone who is. Most likely, at a minimum, you have a faulty voltage regulator, but that is just a guess based upon the info presented. The voltage regulator is a component on the alt; if you replace the alt, you'll automatically get a new voltage regulator too.
