The description you give is a classic sign of problems with a stuck voltage regulator overcharging your system.

Did you happen to notice a sulfur gas smell at the front of the car? Or inside the trunk?

The battery will die due to over charging, as all of the water gets boiled off.

I would replace the (now dead) battery with a new one, check the voltage at rest, should be about 13.2 volts fully charged new battery, start the car and check the voltage at idle and 2k rpm.

The regulator should limit the charge voltage to about 13.8 to 14.2 MAX!

I saw over 16v when my regulator failed. My tach went crazy, the headlight bulbs burned out, and the wipers turned on by themselves while I was driving along!

My $.02, Cooper
