OK, I'm stumped...

JD 112H lawn tractor (nearly ancient)

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

Neither of your links took me anywhere useful. The first link took me to
a model search page, the second link took me to a password reset page.

My bad...sorry. Here's the correct link to the wiring diagram--worked
this time here, anyway...

The JD link I tried earlier appears it only returns to the image when
the search servlet is open--this one appears to work directly to open
the image.

If you're of a mind to actually pursue, the model is a 112 and the
catalog section is 1027 - 112 & 112H (-100,000) Lawn & Garden Tractors..
The Electrical Section is 24 in Sectional index. Not terribly
significant other than it allows one to visualize the diagram more easily.

I don't quite understand this question. Can you rephrase it?

is way to test if solenoid isn't operating might be issue?

Are you asking how to test a solenoid, or whether a faulty solenoid
could cause the symptoms, or what?

Yes...

I'm not positive _what_ I'm asking, unfortunately. This case is
puzzling me in that it's different than anything I've run across before.
I have no power anywhere past the link from the battery +ive terminal
to the solenoid but I can not find any discontinuity in wiring, the
interlock safety switch circuit is functional, etc.

I've just not had any luck in figuring out what is going on.
Contributed to by the fact all the pieces are under the battery mounting
bracket behind the dash panel so it's exceedingly difficult to get to
points on regulator, etc., to even probe.

I was really hoping somebody else could see what I'm not about where
there _should_ be voltage when switch is "on" to aid in isolating why
there isn't anything.

At one point in the process the generator-charging light did come back
on again, but when I then tried to see if it would turn the starter, it
went dead again and haven't been able to get a flicker since. That
occurred when I was checking the transmission interlock switch that
occasionally has come loose or misadjusted so I thought I'd found it.
But, the symptoms are back and the interlock circuit tests for
continuity through both from one end to another so it's somewhere else.

Sorry I don't have a better handle on it; if I did I probably would have
already seen what I'm missing...
