My mower has a 17hp kawasaki v twin engine. It won't turn itself off at the switch. I jumped the switch no change. I found its not firing well on both cyl. No change in Idle when I pull one plug. I switched the two coils and the problem switched sides. I replaced the bad coil and it didn't help. coud the other coil be bad two? Any help please I'm stumped

Is the kill switch lead wire plugged into both modules??

Are both modules installed correctly?

They are usually marked with an arrow that shows the rotation of the flywheel when they are installed properly.

There may be a diode to the kill switch on some, but there is not any on the kill lead between the two coils. A simple continuity test from the kill switch lead wires that plug into the coils and the wiring harness will determine if this is the issue preventing the engine from shutting down.
