Electrical short???

There will be a key way in the flywheel and in the shaft. and its best to remove all the wires from the reg/rec.

"Try this but not for long just to check, most mowers have a 10 or 20 amp fuse, put a 30amp in that guy and let it idle, then just touch the wiring and see if any wiring starts to heat up or discolors."


What the hell is this...?

Hey Engine Man. I appreciate any comments I get. That was not my response to your reply. Treeninja. And thanks for the advice.

I pulled the flywheel from the motor and did find a half moon key. I cleaned a rat nest from under the flywheel and around the magnets, checked the ignition module continuity and it checked out +/- 10200 ohm. Removed stator and no signs of over heating or bare wires. Battery voltage on black wire to voltage regulator with key on. Continuity between stator leads and ground. Cranked the motor with stator leads disconnected from regulator/rectifier and drove mower down driveway and back (1200 feet) with no problem. Hooked the stator leads back up and blew the fuse trying to crank it. I believe its a bad regulator/rectifier. Can't check voltage of stator lead with mower running because it blows fuse. Any thoughts before I buy a regulator/rectifier?

Before you buy a reg/rec check the stator assy, make sure that the coils are not grounding and defective in anyway.
