This belongs to a friend of mine who has done a lot of favors for me. It came out of a flooded motor home.
I would have expected a small wire to be connected to the "battery" terminal of the starter solenoid, do derive 12 volts to operate the generator circuitry. No such wire exists, only the lone solenoid terminal. I see no loose wires or other evidence where such a wire would be.
A schematic would be very helpful in figuring out how the 12 volts gets to the circuitry. Thanks for any help.

The generator is listed in the database under the older numbering system as 4.0BGE-1R/26100F. Go to the Twinslan site and grab a copy of the 900-0186 RV Wiring Diagrams manual. Your diagram number is 611-1180 on page 78.

Pin 6 of connector J1 should pick up +12V bat power,typically at the starter relay FAT bat wire stud.

According to the diagram, the 12 volts to the card is delivered on pin 6 of connector J1 via the "I" terminal of the starter solenoid, not from the "battery" connection. I read no continuity between the "battery" connection and the "I" terminal (the diagram shows one).

Does anyone have the Onan/Cummins part number for the solenoid, or for a NAPA equivalent? I found one on Amazon that "looks" like the right one, but we all know about using the wrong solenoid.

I suppose I could connect the wire from J1 Pin 6 directly to the "battery" connection to see what happens but, since this unit has apparently been flooded, there may be worse problems with the solenoid (for that matter, perhaps a lot more parts) than I currently know about.

The diagram shows the "S" terminal connected to the coil, with the other end of the coil grounded. It shows the "I" terminal connected to the "battery" terminal.

Thanks for the help so far. The diagram is REALLY helpful.

Found the part number myself, by searching "Onan BGE solenoid". Amazon, as well as a few others, had it listed - 307-2570. The part number for models A through E is different - that solenoid has only one small terminal; the solenoid for F models and above has two.

Have one on the way through Amazon - had several dollars left on a gift card, so my out-of-pocket expense was less than $40.00. Don't think a NAPA replacement would be much less expensive.

Thanks again for your assistance. I'm sure I'll be back with more questions. I'm pretty good with the "older" older units (CCK, BF, NH), but not with the "newer" older units.

Go to the Twinslan site and grab the following manuals for your BGE Spec F generator:

965-0128 Operator
965-0231 Parts
965-0528 Service
965-0628 Install

The solenoid shows up as 307-2570 on pages 46 & 47 of the parts manual.

I see nothing sacred about picking up +12V from I terminal instead of FAT bat cable stud. Control board Pin 6 of connector J1 just needs a constant +12V

Besides from right side of schematic 611-1180 it shows an internal connection in solenoid ( high amp relay) between FAT bat +12V stud and I terminal.

Only thing you know for certain is you never are sure what previous owner did.
Trace wires and check that it's wired as per the schematic.

Not sure which Emerald it applies to but there was a replacement control board what required swaping around a few wires to the control board. So likely a good idea to check part number on control board to that in parts manual.

I think this might be it:

Solenoid obtained and installed; solenoid and fuel pump work, but starter does not. Removed starter; has been dropped; magnets in pieces.

I found in the Twinslan manual a part number of 191-1667 for the starter. In searching this number, I find a bunch of them - cheap - but they list multiple part numbers:
191-1630
191-1667
191-2132
191-2158
Is this the starter I need??

Thanks for your help so far. I know a LOT more about the older models than I do about this one.

you have a BGE spec F

Manual numbers and link to them
BGE spec f-k---NHE-spec e-k--EMERALD PLUS--SERVICE--(9-94)--- 965-0528.pdf
BGE Spec F-P Parts 965-0231.pdf
http://www.twinslan.net/~n0nas/manuals/onan/

---------------------------

From that parts manual paper pages 28/29 looks like it calls out starter # 191-1667.
Seen other Onan numbers superseded with another new #, maybe that happened here too, but I'm not familiar with starter numbers.

No real experience with starters, but for what it's worth, a few years ago a Staker bought a cheapie new starter on ebay for $40, it didn't work. Must have been a China job. Staker named Onanparts sells new.

I just searched on Onanparts.com for 191-1667, looks like 191-2416 Supersedes/Replaces all the numbers you listed
