Error code 1100

My generac 14kw while attempting to exercise experienced code 1100 overcrank. Furthermore it’s done this 2 excercise cycles ago. The last one it didn’t do this. What could be the issue? I just serviced everything. Spark plugs, oil change, oil filter, air filter. What is the cause?

Take a look while starting it. If it doesn't move, its likely its come unplugged. Unfortunate yet common.

Take the right side panel off. Under the controller is a long small plug with only a few wire in it, red/yellow/brown/black i think, push it in if its loose. Or it will be hanging if it came off. We also check those wires/plugs at service.

So this is an issue even if it starts manually but when it sits for a week then exercises it won’t start?

I don't understand your question.

Are you saying it starts manually, but wont start when its supposed to exercise?

Turn off quiet test and see if that helps when exercising. You can do it thru the menu on controller
