OT: 911 Battery Acid Leakage, How to treat to prevent further damage Options

[orthobiz]

As some may know, my 911 buddy and I almost didn't make the Parade because his voltage regulator overcharged the battery on his 87 Carrera. We switched out the Optima, put a conventional battery from a FLAPS and limped back to a Porsche specialist. After the Parade trip (awesome!), new alternator installed, what's the best way to treat the front trunk battery area to prevent further damage? There's some blistered paint from acid exposure and I dime sized hole in the carpeting (which he'll probably keep).

This is a primo all-original car. Any thoughts on repainting/refinishing this corner of the car?

Also, does anyone know if a new genuine Bosch alternator is likely to cure this overcharging problem? As best I can tell, it's pretty common for this model.

Thanks,

Paul

House voltage is ac, alternating current, the spikes are absorbed by capacitors that then release the excess to the line when it drops low, thats how ac works. Dc is direct current as in only one way not alternating. The only way I know of to adjust dc is to use a circuit with a varible resistor to absorb the additional voltage. I am also not a ee. Thats just what little I remember from the classes I took 40 years ago. I'm sure a regulating device is available or can be made but the cost is probably about what jake gets for a motor.

I never thought about it but you might could put two regulators in series and the second one might save the battery.

My son bought a suzuki in Oklahoma and we went to get it. While I was driving it back I thought the lights were awful bright, my son said the lights were pretty bright in his rearview mirror on the way back to Waco and that they would vary with speed. I told him the alt might not be charging enough at lower speeds. Two days later one went out while I was checking it out overall. I put a fluke on it and it said 18.0 volts and got higher as I reved it up. The only thing that must have saved the lights on the trip home was the other stuff I was using to bring the volts down. The battery seemed to be okay and we only needed a alternator to get it back to normal.
