Here is some of the insanity that was going on under the hood so it's hard to say what caused what? Miraculously the car started ran and drove and everything worked. I'm not sure if they jumped power around to get things to work but I can't believe that everything would work with that burned up bulkhead? I'm debating on sending the instrument cluster out to get looked at Maybe have them do the modification for the ammeter? Not sure if it's worth it? The only problem the car had is that it was not charging as far as things working properly.
