OK, I'm stumped...

JD 112H lawn tractor (nearly ancient)

Symptom is no voltage in ignition system when turn key to "on/start".

Have had issue on occasion w/ safety interlock on tranny, but that ain't
the problem this time; have tested continuity from switch connection
thru both safety contacts (transmission and blade) to connection at
solenoid and is good. �Plus, when one of them fails to make contact,
won't crank but does get voltage to generator charge light; not getting
that far now.

Question -- is way to test if solenoid isn't operating might be issue?
Service manuals aren't online but here's a link to the parts diagram for
the wiring harness that is a fairly complete wiring layout.

I scanned the wiring diagram I have; don't know how good it'll be but
there's a copy posted here...

Any troubleshooting help/suggestions appreciated...

I forgot to add...............if it starts after doing what I said,
you either have a bad ignition switch, bad solenoid, or a wiring/fuse
issue. I can't tell you which unless I know what kind of solenoid you,
then I could tell you how to test the solenoid.
