Have a late 80's to early 90's 14hp vertical shaft Kohler on a Scag mower. Recoil start only....no battery.
This season the mower deck wouldn't engage.
Determined it was due to very little output from the regulator, further checking revealed about 19 volts AC from stator winding. Read somewhere it should be 25 volts plus.
Stator has about .2 ohms across the wires, neither wire has continuity to ground.
Removed the flywheel and discovered the 6 magnets on the flywheel had become unglued.
Inspected the stator, it appears okay, no bare wires, no indication of shorted windings.
Cleaned the flywheel and magnets thoroughly and epoxied them back on making sure they were equispaced around the flywheel.
Once the epoxy cured I reassembled it. Now the AC output is only about 5 volts at full throttle.
What the heck did I do wrong? Put the magnets in backwards or something else. There appears to be plenty of magnetism in the area.
Would buy a flywheel or stator if it would solve the problem.
Wouldn't it be great if someone had a used one I could install temporarily, if they needed it returned. In such a case I would pay shipping both ways.
