I just replaced the alternator on my van and found that it is overcharging according to the gage(If the alternator was even the problem). It tends to make the liquid inside my battery boil and push it out through the little battery vent(Been through 2 batteries already). I took it to a Mechanic and he stated he checked everything and it's my computer, I wouldn't mind buying another one, however, everyone else seems to think it's a regulator on the alternator and I don't want to spend uneccesary money. Which could it be? Someone please help! Thanks.

It depends on the car. If it's a Dodge, Chrysler, or Plymouth, the voltage regulator is in the computer, and it will mean replacing the computer to fix the problem.
If you could provide the Make/Model/Year of your vehicle, it would allow a more definitive answer.

It is the voltage regulator, depending on the vehicle this could be built into the alternator or a stand alone pack, if it is built into the alternator then it was duff when you fitted the new one, in which case you can get it replaced under warranty and the two batteries it has fried as well.

You got a bad alternator. Even brand new ones out of the box aren't always perfect, and if you got a rebuilt you increase the chance it will be bad. Take it back and get another one. As you suspect, the regulator isn't working as it should, and since it is built into the alternator (unless you are driving a very old van) replacement is the only option.

This is a very rare problem symptom but what i perceive toi be happening is that the voltage regulator contained within the aternator is not working so it thinks the batterey is asking for charge all the time and hence it frys

thats right dude the alternator is cranking out to much juice man like its supposed to crank out 14.2 volts for your 12 volt battery to charge properly. the voltage regulator that is usually built into the alternator has gone haywire just replace it man and you will be crusin again. also you might notice your lights flickering at night bad scene man. get it fixed in a hurry problem solved.

Have the voltage regualtor checked out. You should only be getting about 13.5 to 14V when measuring the voltage at the battery terminals with the engine running.
