Hello, I've been having a problem with my 92 Civic; last week it started to fill with a strong sulfur smell after I had driven for about an hour. When I opened the hood there was smoke (or I guess I should say 'steam') coming out of the battery casing. The battery had heated up to the point that the acid was boiling over and evaporating . . . the battery had a warranty so I replaced it, and the same thing happened with the new one. I used a multimeter and found the voltage to be about 14.4V with the engine off and 17.8V with the engine on (!) So it's obvious that something is causing the voltage to be way too high, I just don't know what it is. I don't see any obvious problems with the ground wire, and there is no corrosion (brand new battery). Since two brand new batteries have had the same result I can assume that it isn't a problem with the battery. Other posts on here have mentioned possible problems with the alternator/voltage regulator?? If anyone has any suggestions please let me know! Thanks, I appreciate any help I can get. Jared
