Generac Model OE6219 SERIAL 7888609 Natural Gas.
Unit starts and runs in manual mode for about 10 seconds then shuts off the overcrank led is lit ,does this constantly, I could hear the starter motor engaging when it was running so I disconnected the trigger wire from it still shuts down after a few seconds.
So far I have replaced the battery / starter motor / and replaced the Brushes and cleaned the slip rings.
Thanks in advance for any help.

That model and serial number most likely came from the engine, and that won't help us unfortunately. We'd need the model and serial number from the silver tag on the firewall panel near the front door.

My guess is that the unit isn't making voltage. When it's running, is it producing power? What is the resistance of the slip rings on the 0 and 4 wires?

Thank you The correct model # 0046753 serial # 4357428 I took off the top cover and found both the neutral wire and ground wires were very loose on the posts .I tightened them up and no longer have the overcrank code but still turns off. I measured the resistance of the 0 and 4 wires going to the Vreg and have about 11 ohms (Cheap meter),

Did you take that measurement with them removed from the AVR? They should be disconnected from the AVR first.
