John,

Very nicely done wiring diagram!  One wire I'm not seeing is the bypass to the ignition coil.

From memory there is a large terminal with a 5/16" stud and nut on the solenoid which attaches directly to the battery.  Next to that 5/16" stud there are two 1/4" spade connectors.  The 1/4" spade connector next to the 5/16" stud is where the "start" lead from the key attaches (usually white/red). 

A lot of times I leave this 1/4" lead unattached when I'm troubleshooting an engine.  A 1/2" wrench proves to be a good "jumper" to short the 1/4" spade to the 5/16" stud - this is a direct way to engage the starter.

The other 1/4" spade connector (furthest from the 5/16" stud) connects to the (+) end of the coil (maybe brown/yellow?).  When the starter is engaged a full 12V is provided to the coil directly from the 5/16" stud (battery).  This is not a critical connection and can be left unattached while troubleshooting.
