hunting is usually caused by fuel starvation not an electronic fault

If the succession is 3-5 sec crank - 3-10 sec pause, it is OK, but the cranking is not successful (the reason should be investigated).
If the succession is more rapid 1 - 2 sec you may have bad PCB control.
SOURCE: Have Kohler 12RES. Gives a CC1 code thenan OC
check your load wires there probaly reversed. I had the same problem friday. The week before the electrican wired it. did the same cc1 then oc. had a generator company come out it was the wireing. my load and netural were reversed.
I finally solved the intermittant starting problem on my Kohler 12 RES by replacing the strater and the starter relay. I was also experiencing the occassional OC indication, red blinking LEDs on the ATS, and intermittent non-starts during the weekly exercises. The problem happened during power outages a couple times also. If I flipped the start switch between auto and run quickly the generator would occasionally start. Once started, the generator runs fine. I ordered a new starter, which included the starter solenoid. By the way, don't worry about the genuine part thing..the old starter was a Delco made overseas. I ordered a new starter online for $85 (6744N) and it was indentical to the genuine Kohler starter. Replaced the starter and it improved the problem but did not totally solve the intermittent starting. Ordered the starter relay (GM49746) replaced it and the problem is solved.

Check gas pressure. Oc is over crank. Means tried to start but did not.
