The stator of a small engine is part of the rotor system that amplifies and directs power from the engine and alternator system to the ignition. Stators are round in shape and fit around the flywheel. They are wound in covered copper coils. If the stator is visibly fried or if any of the stator connections have tested for continuity, the stator is bad. Stators are replaced with new ones when they have gone bad.
Remove the negative battery cable on the engine with an adjustable wrench.
Access the stator, which is typically mounted near the flywheel. This is typically done by removing the alternator cover with a socket set.
Disconnect the plastic wiring harness on the old stator.
Use a socket set or Allen wrench (depending on the make, model and configuration of the motor the stator is inside) to remove the retaining clip or bolt holding the old stator in place.
Grab the old stator, take it out, set the new one in place and then replace the retaining clip or bolt.
Plug the new stator's plastic wiring harness, replace the alternator cover and then replace the negative battery cable.
