THOR #24292
generator starts and quits

Thor Gemini 2018 23tr w/cummins 36KY 26120R generator.
I get a 12 fault at intermittent times when starting my Generator. I can usually correct it by turning off the main gen circuit breaker at the generator.
The action to take according to the manual is to test voltage between two posts that are on top of the generator and unavailable due to how the generator is mounted under the RV. Any ideas on how to correct this fault?

Be sure fuel pump wires are in tight.
