The engine is failing to run after a commanded start. Repeatedly.

Are there any faults listed on the control display? If display is dark then likely a battery issue. Check battery voltage with a Digital Multi Meter (DMM). It should be at least 12.5VDC.

Sounds Like possibly the regulator is the issue.
Flightsystems Can test these to see if it is good or not.
also here is a link for the service manual

the parts manual is a tp-5317 which I do not have . You said its a dec2? or a fast response 2? What is the part number off the main circuit board in the control box?

if you have an scr pack, that has 6 pins, there are two for ac, two for gates, and two for the excitation field.
The two gate wires come off your adc controller.

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.

Safety shutdowns:
  1. Loss of coolant
  2. High water temperature
  3. Low oil pressure
Likely one of these. If no indicators at a panel check at the connector.

There might be two reasons for the failure of generator auto start.

1. It is the ATS automatic conversion control device that does not issue the start generator command after the mains power failure or phase loss operation, or the self-starting relay failure, which causes the generator to not start itself. This situation is relatively rare.

2. It is the generator start battery failure, and this kind of situation is relatively more.
