I will start out by saying that I am grateful for everyone's help and suggestions on my problem. I have driven trucks, but buses have their own unique systems and problems. I received my wrenches and removed the bolt. However the hidden one on top had a stripped head. I tried various tools and methods. In the end I broke the starter ear with a chisel and bottle jack to remove it. I ordered 3 new bolts at my Bluebird dealer. I installed the starter and guess what? It still did not start. So $500 in parts and around $80 in tools and no go. When I removed the old starter I found a small wire attached all by itself. I hunted on the net and found a site that showed you how to rebuild the starter. On the site that wire was referred to as the start wire. I had asked everyone if there was a way to short the starter, but no one would tell me yes or how. I took the old starter and tried it. It worked!
So today I setup to try it for real. I plugged the bus in because it was about 25 here this morning and I wanted to make sure I gave it all the help I could. I had my wife run the key and preheat and watch the gauges. I shorted it and it fired and ran instantly despite sitting 2 months. I would guess that most likely the neutral start switch is gone or a wire is broken on it. I have seen this mentioned on other forums. I will track this down and let people know what I find later.
So in the future if someone asks about these starters please let them know you have to look for it but you can short them. Also refer them to me and I will lend them my knowledge about what I have learned.
