Craftsman Koehler Command 16hp OHV no spark

[Charlie11]

Craftsman 42” w/KoehlerCommand 16hp OHV model 917271030 stopped in mid mow. Not overheated, Turns over but has no spark. Replaced coil 2021.

attempted solution:
-Reset gap between coil and flywheel
-lightly sanded coil/flywheel magnet
-checked fuse, not blown

Still no spark.

 

[Rivets]

Remove the kill wire from the coil and check for spark. If you have spark, your kill wire is chafted somewhere, cause it to ground out the coil.

doesn't that have an ignition module and a coil? Are there any kill switches on it - ignition or seat etc.?

[Charlie11]

That’s where I’m ignorant. Which one is kill wire?

Yes, seat, mower engagement, key switch. Not sure about efnition module but yes, one coil

 

[Rivets]

There are two wires attached to the coil. Heavy one going to the spark plug and a smaller one, which is the kill wire.

The wiring diagram for your mower is on page 31 of this manual

See the box labeled "ignition unit"? This represents your engine magneto. The body of it is grounded (represented by the right wire), while the kill wire goes off to the left. If that kill wire obtains a connection to chassis ground, it will kill spark. To test if you do in fact have a ground on that wire, I would get an automotive style test light and hook the clamp end to battery positive, so the light will illuminate if you find a ground.

Ok, ill let you know what happens. Thank you. Will be tomorrow.

According this mower came with a Kohler CV16-43514. This has a DSAI or SAM ignition system and not MDI system. Depends if it been converted or not so will have two control wires or three controls wires plus the HV lead for spark plug.

The Sam control box is no longer available which is why Kohler is now sending out the DSAI conversion kit when the control box fails.

This is the SAM ignition module.

And this is the DSAI ignition module conversion kit
