I find it hard to believe that with nearly 2 dozen folks looking at this post, that the only information anyone can offer is the thought that I may have done something wrong when I changed out the battery cable ends. I'm brain damaged, but not brain dead. I've never had a vehicle of any sort act like this. Everything was fine one moment, and when it went bad, it went bad in a flash. No indication that there was anything wrong. I've been through my service manual several times, and nothing is mentioned about these symptoms, so I guess I'll just spend some more time chasing a gremlin.
