Small Engines (Lawn Mowers, etc.)/kohler cv22s


QUESTION: My kohler has a cv22s with smart spark ignition.  I believe both coils are bad.  Is it possible to convert it to a fixed ignition system or do I need to keep the smart spark ignition?

ANSWER: Did you download the service manual and ohm the coils to make sure they are bad?  See page 42.
Are you sure a safety switch is not causing the "no spark" issue?

QUESTION: I completely separated the engine from the tractor.  I have power to the modules from the SAM module. I also did the ohms test.  I will do it again just to make sure I did it correctly.

While we do find a bad coil every now and then it is pretty rare for both coils to fail at the same time unless 12 DC was applied to the coil(s).

On average, we probably sell less than a dozen coils...they rarely fail.  Most riding mower spark issues are caused by a safety switch or bad oil switch.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
