I have a 1989 Honda Prelude with some sort of electrical issue. I keep smoking may batteries. I just got a new one and after a week, it is starting to do what my old battery did: smoking sulfuric gas out when I drive.
Like many of these problems, I only have clues to work from. SO here they are:
the battery is dead every morning. Starts up fine all day long. But, totally dead or nearly so every morning.
I have blown the battery fuse (fusable link) several times. Oddly enough, the last time, it was when I tried an AM restart. I had parked the car normally the night before after driving 30 miles and in the AM, fusable link was blown.
One other possibility. I replaced the alternator about 4 months back. When I ordered the part online, it came with a 4 prong interface plug. My car has a 3 prong interface. The shop was not sure what to do with the 4th wire. They/I assumed it was some sort of signal wire. So it was left hanging and electrical taped off. My alternator light has been on ever since. Since everything worked OK, I asumed that this had to do with the hanging 4th wire. The alternator recharges the batter just fine.
