Charles,
Unless you're charging the starting battery you do not need to have
the VR hooked up and in fact it has been removed by most people that
use the new converter/chargers.

Ok I'm looking at a wiring diagram out of the "Onan Major Service Manual for the NH Power Drawer on page 53.
It shows that there are 2 connections to VR1 (the voltage regulator).
The VR1 terminal with one connection is a wire going to control board pin 5.
The VR1 terminal with two connections goes to Control board pin 8 and a second wire going to the internal alternator.
I do not have a picture of the actual regulator. I just have the wiring diagram in front of me so I can not tell you which pin is which on the regulator.

Why, oh why, didn't Onan use color-coding on its
wiring or at least, individual wire numbering?

It is color coded , "Green" so you know it is Onan wire.

Done did that...cant tell..
I have two larger wires that are the same size, female connector
there is 1 wire slightly smaller, female connection,
There is also a male connection with a round sleeve on it..
Can someone definitively tell me either..
which two to hook together abeit disconncted from the VR and which ones then dont have any connection but to tape up..
or
Which wire goes on which terminal and what does the male connector with sleeve go to? (Not fuel pump. I have a black wire going there).

All my Onans have single color wiring harnesses. (High temperature wiring.) There also appears to be several different versions of the harness... the Voltage Regulator wiring is different in some of them.
I suspect you are going to get out a meter and trace out your wires. (Sorry to tell you this but it is a good skill to have.)
Do you still have a fuel shut-off solenoid? It has wiring very much like the fuel pump and might be where your "extra wire is from. (It is often removed. There IS a reason for the solenoid, but many say you do not need it.)

Yes, but two of those wires must be connected together for the Onan ti
run.

Thanks for that info, Emery. When Charles
comes by tomorrow, we'll go down to my
coach and eyeball things in person. THEN,
we will go to try to duplicate things on
Charles' coach and see what happens.
Breaking news updates as they happen!
