I just rebuilt a 99 Kohler CH25 with SAM ignition. I tested the ignition modules with a multimeter and it looks like they are in spec (although I am not 100% convinced the readings are correct). I used a spark tester on both modules and a couple of times I would get a spark. Nothing consistent, though, and the spark appeared very weak. I isolated the coils from the rest of the electrical system--nothing. Changed the flywheel --nothing.
I had a replacement motor to swap parts, so that gave me four ignition coils. I can't believe that all four ignition coils are bad. I can't get a spark to save my soul. The engine does have the SAM, but if the coils are isolated from the rest of the wiring system, shouldn't I get a spark?
Has anyone run into this issue and then resolved it? Any info is greatly appreciated.
