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. enblethen • View posts Moses Lake, WA Senior Member Joined: 01/05/2005 View Profile Posted: 02/02/20 03:32pm Link  |  Quote  |  Print  |  Notify Moderator See if this works for you!Service manual Bud USAF Retired Pace Arrow 2003 Chev Ice Road Tracker MountainAir05 • View posts New Mexico Senior Member Joined: 01/27/2007 View Profile Offline Posted: 02/02/20 03:35pm Link  |  Quote  |  Print  |  Notify Moderator https://www.bing.com/images/search?q=onan+microlite+4000+4ky+fa26100j+wiring+diagram&id=4263C7210ABA220D6B187BE7BC2B37CA22E92750&FORM=IQFRBA http://rvwithtito.com/download/Onan4000MaintenanceManual.pdf myface • View posts Florida Full Member Joined: 01/08/2020 View Profile Offline Posted: 02/02/20 04:01pm Link  |  Quote  |  Print  |  Notify Moderator I got the maintenance manual, but all of them shows only 15 pins.

How many wires come off your circuit board?

Diagram 12-21 is for 60 Hz. Others were for 50 HZ. Pin numer stays the same. myface • View posts Florida Full Member Joined: 01/08/2020 View Profile Offline Posted: 02/03/20 05:46am Link  |  Quote  |  Print  |  Notify Moderator 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. myface • View posts Florida Full Member Joined: 01/08/2020 View Profile Offline Posted: 02/03/20 05:52am Link  |  Quote  |  Print  |  Notify Moderator The pics are in http://jestarkel.com/pics/1.jpg and http://jestarkel.com/pics/2.jpg Reply to Topic  |  Subscribe  |  Print Topic  |  Post New Topic  |  Oldest first Newest first  Page of 4   Next Open Roads Forum  >  Class A Motorhomes  >  Maintenance Issues & Tips  > Onan microlite 4000
