I suggest that you bypass sensors by using jumper. Need to determine if it is normally open or normally closed switch, or a variable to ground as in the case of temperature probes.
Test accordingly. Will it run if you bypass the sensor / switch? You can make your own logic test for this. That I worked for Kohler many years ago only indicates my general respect for the company and engineers and sales people, but like
Jaguar, and all other systems they are kind of lacking in the
Navy Way... designed by genius to be operated by idiot... under any condition is not on the page 100%. Sometimes the design was in error, not the repairman and guy on the ground that needs to fix it. A team response works best. Hats off to the forum and its leaders! Kohler manuals are usually generic from my ancient experience. Keep
computers away from
marine engines. Analog worked. Keep it Simple.
