[8D] my battery is boiling like crazy ,i assume the voltage regulator is bad is this an easy fix. i hate to replace the entire alt. since it is putting out an abundance of current.please help before the acumulating hydrogen gas blows my hood off thanks everyone

 

Be very very careful if you have to jump start your car. You have a fire hazard there!

 

What is the charging voltage?
Maybe someone overfilled the battery?

 

With the engine cold (overnight is ideal), check the electrolyte level in each cell. Wear acid-resistant gloves & eye protection; the electrolyte is extremely acidic/caustic. If the level is too high, use a syringe to remove excessive fluid or have it done at a shop.

If the electrolyte level is not too high, yes the voltage regulator may be shot and overcharging the battery. If you have a digital multimeter check for voltage; it should be 13.5-14.0V or somewhere around there. Over-voltage will only give you negatives.

A voltage regulator is sold separately, but considering its price and overall effect, I would just replace the alternator with a rebuilt Bosch for about $230 with core. Pep-Boys sells them with lifetime warranty.

Tech and JPN hit the high points. The main thing you need to do is observe proper personal safety, and for God's sake don't smoke while messing with the battery <grin>
