Said it would not CRANK, not that it won't start. I would look and listen to see if any relays are clicking, if so there would be the place to start taking meter readings to see if power is getting through. Most likely the problem is in the areas you were working in and you probably bumped a wire connection and disconnected a plug or broke a wiring connection. Do you have the chassis wiring diagram from the chassis builder? It is a great piece of paper to have and Itasca will not have modified it to much.
