Kawasaki FH680D weak spark
I have a Kawasaki FH680D-ES04-R that backfired and now it will not start. It has a random, weak spark. Pulled the flywheel and cleaned the charging coil, checked and adjusted the spark plug gap, replaced both coils and the voltage regulator. The seat switch and brake switch test good. I have been told that the flywheel (magnets) could be the source of these problems. Has anyone had any experience with this? It is on a John Deere 737.
