Sovereign Kohler Command 18 magneto

Recommended Posts

Ok guys finally figured out why my command has been running bad. Thought the fuel pump so put in new one. No change. I feel stupid but it was only running on one cyl. Did compression check both sides good at 150psi. Only spark on one side. I have been told it's the magneto that went bad, I confirmed by pulling the white wire and still no spark. Local place told me that test trick. I guess part # is 2458445 and they are about $50 each. I have installed the clean out blower housing mod. Local shop said I would have to pull the motor to change them out even with my kit installed. Agree? Is there anything else this could be or just a bad magneto?

Sounds like you've isolated the problem. Could be a broken wire - coil wire would be most likely I would think, but it could be the spark plug wire, maybe at the magneto. I agree with the shop, I don't think you'll be able to change out the magneto without removing the blower housing even with the clean out windows. Here's a couple pics showing the location of the magnetos:

Thanks Bill, I think I will be pulling the engine and blower housing and least none of the bolts are seized as I just put the clean out kits in a few months back. Maybe I can send a few things out to the chromer while she's apart :)
