A few weeks ago, I posted about the battery in my van, how it was heavily corroded, and how cleaning it seemed to clear up some electrical gremlins I was having. My wife phoned me last night when I was out of town to say that the van now will not start. I got home today, and sure enough, there wasn't enough juice to pop the door locks. Turning the key caused a ratchety clicking noise to come from the area of the fuse box in the pax compartment. I jumped the van from my VW, and it started right up. I let it run for about 15 minutes, turned it off, and it started again. The positive side of the battery was low on water, so I topped it off. Two hours later, it's dead again. It seems to me that it's just a case of a dead battery that won't hold a charge any more, but I've never heard that clicking noise from the fuse box before. Any ideas?
