Breakdown happens

I was at the end of a dash at a local police station, got back into my car, no start. Just like that. So I call my service garage he sent a tech out. The wire on the starter was loose. I was able to drive it yo the shop where they found out the bolt on the starter was rusted and was not letting the wires connect properly. $ 300.00 later all fixed. So much for profits today. There is always tomorrow
