Our '78 403 will not start. I drove it home Friday. It started normally. I stopped for gas, and it started normally after that. On Saturday, all I did was generator maintenance, no work at all on the coach engine. On Sunday we got in it to take it back to storage and it won't start. The battery is fine. There is no "click" sound at the starter. I tapped the starter with a rubber mallet, still nothing. I read through this thread about a 455 that would not start.

I tilted the steering wheel all the way forward per Jim Hupy's suggestion, still no start.
The headlights do not dim when I try to start it.
I jumpered the double purple plug to bypass the neutral safety switch per the Starting Circuit Diagnosis chart on page 6Y-62 of the maintenance manual. Still nothing.
I am ordering a new starter, but I'm not convinced that is the problem. How to I check the rod that extends down the steering column from key mechanism? Any other suggestions?
