This thing is driving me nuts!!How do I set it so it does not overcharge my batry.. Can I try this at home or do I bring it to a professional? How then do I know its done right? I have had several people look at my 'overcharging battery/problem' -everyone gives me advice that sounds good in theory AND MAKES GOOD SENSE but doesn't solve the acid mess on my battery tray. Currenly on the car in a Delco reg that is 3 weeks old from Year One. I need an expert. Thanks in advance.

I had a similiar problem and it was the alternator. The diodes were shorted out and it was pumping out too high voltage that cooked the battery. My amp gauge was doing the wild fandango!

I believe as long as one doesn't have over 13,8 volts across the battery at charging time with no accessories on, then shouldn't be a problem.

The battery tray is being corroded by the fumes, not from the acid boiling out, unless you really do have acid boiling over, then, that's a real problem and I would check the regulator to make sure it's doing it's job.

Eastwood sells a mat for the tray and sets underneath the battery to absorb all the stuff, you might give them a try.

I am not worried about original stock look so I went to a one-wire alternator. This is an awesome change. Remove the voltage regulator and connect the red wire to the one-wire alternator. Done deal. No more problems...and most of the time more amperage too! I picked up a rebuilt 80amp one-wire for $49. I think this is the way to go.
