A new voltage regulator corrected the same problem for me- figured this out after frying the new altenator.

Attach a volt-meter (if you don't have one, buy a cheap digital one) to the batt posts, with the engine running, warmed up, at cruising speed/rpm you shouldn't have over 14.2 V, if so replace voltage regulator. If it's 13.8V to 14.2V, have your batt tested. If it's under 13.8V have your alt and batt tested.

If you don't have a wire running from the frame to the engine, you may have problems with the charging system. It needs to know where ground is.

My buddy bought an 80-something rustang from his sister, who said it always cooked batteries. We hooked the (-) to the frame, and never had any more problems with batteries. The rest of the car, on the other hand, lived up to it's name...

71GMC_3/4T has a good point! With that voltmeter you can test your grounds. Set the scale for 20VDC and attach one lead to the neg post of the bat, then start vehicle and turn everything on (headlights, heater etc) using the other lead from the meter touch other grounds such as the engine block, radiator support, frame, cab etc. You should not get any readings over .5 volts if all your grounds are good. If you get a high reading (as an example) when touching the radiator suport you need to clean or replace or add a ground strap from bat to rad support.

That is good advice, but you should probably count on a new regulater and probably a new battery now too.

Oh, clean up everything that your battery puked on too.
A solution of baking powder and water will neutralize the acid, and then rinse it all real good.
