I have an Onan Marquis 3, it just stopped running, I could not get fire to the plugs so I replaced the coil, capacitor, ignition control, plug wires and plugs. The motor cranks over and over but no fire to the plugs. Any ideas???
Re: onan generator Brian 1-18-11  
I have an Onan Microquiet 4000 generator, model number 4KYFA26100K in my 2005 Winnebago Sightseer.
It started surging this season. I took off the access panel and noticed that the choke assembly might possibly be broken. The square piece where the choke wire goes through is hanging on the wire and dancing around as the engine runs. The choke is open on the top and hot air pours out as it runs. I was looking for an exploded view of the choke assembly so I could see if anything was missing, or if it just fell apart and could be put back together. Please help.

Re: onan generator Nolan 6-2-09  
I was drydocking. Was running tv and air conditioner. My digital monitor went to beeping and showing fault problems. The monitor was showing 157 volts. I immediately shut the generator down because it generally shows between 116 and 118 volts. A week later I have cranked the generator and it is now showing 124-125 volts. Is this too high to run tv or air conditioners or should I still not run generator? The generator is an Onan Emerald Plus, 6300 Gen Set.

Onan generator. Nothing happening when pushing the start buttons
Re: onan generator Bill Cooley 7-21-03  
You might check the low oil preshure cutoff switch. I have had one stick and the gen set will run in "start mode" but when you release the start switch it will stop.This is because your switch is stuck open.

I have an Onan Emerald I genset that stops after it starts and continues to do so. I have replaced the fuelpump, then checked wiring fire, did a straight wire to hot wire that allowed me to start the motor, but no generator power. I have no wiring schematic. Can you advise me as to what might be the problem?

Re: onan generator Mike 1-2-06  
I have an early 80s onan 4kw in my coach that has recently started a somewhat unusual problem. With full 5 minutes of spuratic rpm fluctuation, the genset finally smoothes out to a somewhat stable run but heaven forbid you turn on a coffee maker or anything else with what I would call a very low level of current draw and the generator is back to it's influx of rpm and obnoxious shaking. My diagnosis is a fuel problem of some sort but I have a full bowl on the carb and good flow out of the pump. So before spending money on moderetly educated guess' I am hoping to get some suggestions on were to start. Thanks Mike

Do you have avaivable wiring diagram for onan generator 7.5mdje -3cr/2268b serial #1269184300
Re: onan generator wiring jim pat 4-23-09  
I need info on getting 240 volts and 120 from the Onan. Have 4 wires coming in the box, M1, 2, 3, 4,
Now M2 and 4 are joined and show 120 volts and M 1 and 3 = zero volts.
That would be negative and positive for 120 volt system?
For 240 M1 for one line, M4 for the other leg and M2 and M3 together for the negative?
