ehh, when the car is running, the alternator is supposed to recharge the battery.

So when your car stalls and then does not have enough juice to get it started again... there must be something wrong with your alternator or something else in the charging system. I would take it up to advance auto parts and have them do a FREE alternator and battery test.

Just out of curiousity, isn't the voltage regulator built as part of the alternator on these cars?

I believe most cars' alternators have a built in regulator. Also, don't quote me, but I think some batteries might come without water in them. Read the battery instructions and see if you need to add water. Check it anyways.

This came up a few weeks ago. Check your body/frame to engine ground strap. Sometimes they can screw with your system. Most get left off during an engine or tranny swap.
