Thanks, I just bought it. In my contract the promised to fix it. I did finally find a web page that listed the codes. They checked and tightned everything down and everything checks out fine, the light hasn't come back on. Either the battery was low enough or a bad connection somewhere along the line may have cuased the problem. I had an 01 jeep that would have a similar problem. On the jeep I changed out a battery cable and that fixed the problem. The van only has 50K on it and the battery looks new and the alternator "SHOULDN'T" fail at this point. We will see.
