Apparently. I Have a 6k manual, but the resolution is too poor to make out the pin numbers. What manual do you have that shows the run indicator lamp
(and/or Hobbs meter) of the remote panel wiring connected anywhere but pin 6?

From the 4k ops and parts manual, page 11, figure 10:

Of course, there is this one that shows pin 6 and 9 being electrically identical (but the remote panel still connects to pin 6):

I really think the run indicator on the remote panel and the Hobbs meter should be connected to pin 6 so that it is independent of the revision of
board you are using.

Ah Ha! We've found it! I don't have time now to do the research to sort
it all out, but there ARE differences in the manuals!

The schematic you show IS different than that I referred to. And yours is
obviously the one from which I drew "my" version because it shows (6)
connected as I just "corrected" to agree with the other schematic.

I'll try to get back into this tomorrow and identify which manuals have
which versions.

Thanks everyone. I DID connect the running indicator light/Hobbs meter wire to the #6 pin on the control board as suggested. Everything works as it
should.

OK, here's the answer to our conflict:

There are at least two Onan service manuals, with the ID numbers 6A73 and
10A73. They're posted here:
https://drive.google.com/drive/folders/0B3XquSIYjDleMTBNZ3hoQTJnYU0?usp=sharing

Also posted there, extracted from each of the manuals, are the
corresponding wiring diagrams. If you examine them closely, in light of
our recent conversations, you'll see that on the 6A73 schematic pins 6 and
9 are directly connected to each other and to the ignition coil, the fuel
solenoid, and the fuel pump. On the 10A73 schematic, pin 6 has been moved
to the junction of CR5, CR7, and R2.

It's obvious that the purpose of the change was to provide the isolation
some of you want of the RTM from the starter. Too bad Onan never announced
(or, more likely, we late-comers missed) the change. I suspect the 10A73
configuration is what most of us have -- 'tho' I have no evidence to
support that.

My modified wiring diagram was obviously taken from the 10A73 version --
despite my having rather badly screwed up the flywheel alternator
connection. I'll get around to fixing that soon.
