How have we gotten to a siezed a/c compressor from a bad alternator. Ok remove the belt, still don't see it will help, since it's unlikely that is the problem from what I am reading here. If the alt failed, was replaced, car ran sluggish, battery drained out, then the engine siezed??? So did you say the car would not start...would it turn over after recharging the battery? I am searching for some logic here. All the years I have worked around cars and on my own, and with the information you gave, just does not make sense. Is there a domino effect or is it were getting close to Halloween.
