Need a wiring diagram for a onon marquis 5000 generator Model# 5bgmfa26105f Serial#c953351341

Unfortunately, Generac does not provide wiring diagrams for their products. You will need to contact a local Generac dealer or service center for assistance.

A little confusing I found 3 fuse box diagrams which cover your car. Not sure but hope it helps.

Sorry we do not have that manual here, you will need to order it from the manufacturer.

There are many possible reasons from stator output voltage to sensing, to fuel to control boards. A good place to start (as the unit does run) would be with the fuel system, if it has sat a long time it won't help. Also the fuel filter. try conencting to an external fuel tank versus the vehicles, as sometimes pick up tubes in main tanks can be an issue. Also check the correct oil level and viscosity / and oil pressure switch. Failing that I recommend a service center, as there really are so many causes, I cannot list all on here.

Couldn't get you a wiring diagram but the contact info should get you to someone who can. The other links will get the manual and parts breakdowns.

Give me to full model and spec # and I will email you a service manual.

Test the solinoid with an ohms meter and if the circuit is open replace the solinoid.

To find a manual for this generator go to powermate.com and search your model and serial number. Good luck!
