Kohler 10EOZD Diesel Generator
Went to start yesterday and the starter would engage, engine try to spin over, starter disengage. Engine would turn about 10 degrees before stopping. I took a screw driver and manually spun the engine to make sure nothing was locked up. Seems fine.
Tried again, same problem. If you hold the start button, it will show CC1 on the status display while trying to crank. Then display goes blank when starter stops. If you keep holding the start the crank cycle repeats after about 1 second and then stops again immediately. Keeps repeating.
I have very limited access (basically no access) to the back side where the starter is at.
I don't believe it is a fuse problem since it does try to crank. Not sure if it is a relay problem on the controller board since the starter immediately disengages. Not sure if it is a starter problem not properly engaging.
I also am not sure of the starter part number in the manual. I believe it is 344743-P but not 100% sure and can't seem to find one online by that number that is available from a reputable place that I normally utilize like Marine Parts Source.

Anyone run into this problem before on this or similar generator?
Anyone have an idea of the part number for the starter (not sure I want to buy just to find out that is not the problem at a cost of several hundred bucks).
I will probably be calling Marine Parts Source or Kohler tomorrow to see what they say.

Thanks
