I have Onan Microlite 4000 4KY FA261100J. Does any one have wiring diagram for that genset. I have 3 different but none shows wiring for mine. What is most confusing, all shows 15 pin connector and mine have way more pins going to computer. I am having problem with fuel shut off solenoid - not getting voltage. Previous owner replaced carburetor and mess up the wiring going to fuel shut off solenoid. I am trying to locate the pin so I can bypass the wire and run new one. The gen will run if I jump 12v to that solenoid.

I got the maintenance manual, but all of them shows only 15 pins. The computer is 300-5046. I can not locate wiring or pins for that computer.

I am guessing you have Spec J.The circuit board is updated to a 327-1413RV
Electrical drawing in manual appears to be 12-16.
How many wires come off your circuit board?
Edit It is diagram 12-17

Let me try it again!
Diagram 12-21 is for 60 Hz. Others were for 50 HZ. Pin numer stays the same.

I do apologize for not responding. My internet is buggy. Is there any way to insert image to post?. My computer have 23 pins, but the connector use only 18 pins. This is where my confusion begins. The only way for me to trace the wire would be to take the carburetor and manifold off. I will try to upload to one of my website and post a link.
