At work now, will post up more info after work. Cube relay is a standard 4/5 pin available at most parts stores.

Maybe if you can post pics of your old boards that will help people here ID them.

Here are photos of Onan part with 332C1491 stamped on board. Another Tech said it was part # 300-0935, maybe?
I can find the two control boards but this part I cannot find. I may have to do a 12v cube relay as the replacement. Can anyone ID the part?
Thanks,

Can anyone tell me the part number for the above control starter adapter Onan part. This is the part that was on my Onan 4.0 CCK R as an added panel part. I need to replace for outside connections for Onan splitter. Does anyone know this part and where I can buy one as a replacement.
Or does anyone have another part that I can use?
I want to get this Onan back together and running.
Thanks,

The board you show in the first three pictures is listed as A2 Control Start Adapter on the wiring diagram. The part number is 300B935 or 300-0935. It is a simple board with only two relays. Why don't you clean it up and see if it works? It can be very easily repaired by anyone with electronic skills.

Ok finally found my notes and successfully translated chicken scratch... Pin numbers are terminals on the 859 board. Smarter man than I would probably use a socket for the relay, but I used crimp terminals - soldered and heat shrunk. Seems to be doing ok so far.

Thumbs up Re: Onan 4.0 CCK 3CR Broken Control Boards

Hello Again, I finally found all three control panels for my Onan Gen Set. I have all the wires numbered from the old 300C859, and the other two smaller boards. I have started running the new brass connections from fuel tank to cut-off, copper fuel line, to metal Fram filter to fuel line connection to Onan Gen Set. I have all control boards connected back to original metal housing. I have started making connections to new Onan control board. The new Onan replacement board has different connections. Does anyone have the old Onan control boards to their Onan Gen set that is a 4 OC-CK-3CR- 810? I would like to have a print out to make sure all the connections are correct by connecting existing wired numbered wires to the correct number on new replacement board.
If I had the wire descriptions for the old board I could double check to make sure the wired-numbered wire goes to the correct connection. Does anyone have an old listing for each connection for their old Onan 300C859 control board. I was hoping to use that description for connections to double check my new connections. I had a fall in the snow from winter and finally getting back on my feet. I have started labeling the wire-numbered wires, as Starter Solenoid, Ignition coil, etc. It is going slow, but I am making progress thanks to all your help and support.
Al
Thanks for all your help.

Photo Re: Onan 4.0 CCK 3CR Broken Control Boards

This is the old Onan 4 OC-3CR-810 control board 300C859. I have all wires numbered with numbers for the old control board, listed with photos.
Does anyone have the description for each wire so I can match up to new Onan board 300C859. The new connection descriptions are in first photo. Can anyone help me double check my connections to the new board. I have the electrical schematics but no connection listing for each terminal. I want to connect all wires to new board. I have all copper run with fuel filter and cut off. No leaks, I am so close now.
Thanks for all your help and support.

Does anyone have a description per wire to old control board 300C859 Onan Gen Set. I want to hook up cables to new, replacement control board? The board has different relays and different connections. Can anyone help me double check all my new connections to new replacement board?
Thanks for your help.
