M696 Have a bug?(starting issue)

[Howie]

Unfortunately your problem is intermittent so it won't be that easy to find.  Cary a meter with you and try to test while the problem is happening.  Think of it as a voltage "goes into" problem.  Goes into the solenoid but doesn't come out, bad solenoid.  Goes into starter, no crank, starter problem.

I found it. Starting problem - corroded kill switch.
Starter problem - starter contact was not covered with it's rubber cap and corroded.
