Wheel horse 418 c Kohler m 18

[Ex wh1257 61]

Hello everyone, I have a problem with my Kohler 18 m motor. There is a 25 amp fuse. After rinsing it with water, it unfortunately blew after drying. I thought it would be fine, but not, so every time I turn on the ignition the fuse of 25 amps broken after measuring the wiring harness I came to the conclusion that if I disconnect the plug from the motor it does not break, the plug goes to the stator part of the charging current where there may be a short circuit somewhere. thank you in advance

I will not be the ignition that is shorted. Do you know where the voltage regulator is? Try disconnecting it.

This is not going to help you with your issue, but what do you know about that flywheel? I see that it has no cooling fins and hope this is not going to become an issue cooling the engine.

I put the cooling fins off

I have a 417-8 with a series 2 KT17 that was popping a fuse every time I turned the key. (Got it that way).

Found out it was a loose solenoid that the PO changed and never tightened to the tower.

Worth a look

Any loose or corroded connection in your electrical system will cause a voltage drop and unwanted heat. The fuse holder and most of the electrical components live near the battery and have been subjected to battery acid fumes for several decades resulting in some corrosion. I would recommend that you use an old tooth brush and some baking soda mixed with a small amount of water to clean ALL electrical connections including grounds. Ad a dab of dielectric grease to each connection as they6 go back together to prevent future corrosion.That will be the best $ 5.50 you ever spent.

I think the stator is broken, I took off the flywheel, the magnets were all broken, pieces everywhere, resulting in the stator being broken, and I have since installed another stator, but now comes the difficult work of attaching the magnets to the flywheel, someone here. experiences with it?

If the magnets are badly broken maybe a replacement flywheel??  Other wise piece the magnets back together and epoxy them to the cleaned up flywheel keeping a gap between them.

I think the magnets are directional if you glue them back on.

I re-glued one once, made spacers for between the magnets.

I can't remember what I used to clamp the magnet snug to the flywheel, maybe "K" clamps?
