Before installing your new stator

• Check the AC output of the stator.
• Replace any burned or corroded connectors on stator and regulator/rectifier
• Check and repair any melted wiring.
• Use hi-temp dielectric grease on all connectors

Our stator may use a different wire color code than your original.
All of the wires are installed in the correct order; please do not change any of the wiring configurations.
This stator is designed as a direct plug-in replacement and should be used as such.

When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible no less than 0.010?.
