Kohler 10EOZD Diesel Generator - Start Problem

[Rocketman]

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

You didn't mention it but have you checked the health of the start battery before going further, cables/grounds etc.

What did CC1 indicate?

[Rocketman]

Battery is good and verified.
No contact or fuse issues. Verified.
CC1 indicates Crank Cycle 1.
Ir shows this while cranking. I don't believe this is an error code but rather a status while cranking.

No expert here, but I'd remover the battery cables to it, clean both ends, clean up the studs and the whatever the ground is connected to, make sure the starter mounts are tight. Next thing I'd check is the solenoid and it's wire soundness.
But again, not a genny pro.

[Rocketman]

If I could easily reach the starter I would remove and test.
Hoever it is on the back side of the generator and a completely blind access.

I am guessing it is not the starter, but a cable corrosion issue. Let's hope at least.

Are you trying to start at the genny or at the cabin panel?

[Rocketman]

Was trying to crank from both positions.
Found it. Bad connection on the starter relay at the control panel.
Cranking fine now.

Awesome.
