Detroit Diesel won't start from ignition switch

[Newell Boss]

The engine will not start from the Ignition Switch in the front, but all the lights come on and everything seems to be working OK; and the Allison Transmission is set on gear/N indication.

The Engine will start from the Maintenance/Service area in the rear of the coach but not from the ignition .

Does anybody know why the Engine will not start from Ignition, but it will at the Maintenance Panel. I've checked all the fuses but to no avail. Is there a master reset for the engine/transmission? Can I reset by removing the Battery connections (Negative First/Positive Second)?

OK, This one was easy... There was a Wire that I had connected to the Positive on the Chassis battery, when in fact this should have been the Ground connection... Once I moved it, the coach started right up.

I just didn't have this ground connection right.

Works now.
