Specifications:Dimensions:Interior diameter: 42 mmExterior diameter: 115 mmThickness: 24 mmLength of wires stator to grommet: 150 mmLength of wires grommet to plug: 1470 mmOther specifications:Wattage: 650Number of wires: 3Number of plugs: 1Number of pins: 3Number of poles: 18Wire to wire resistance:Alternator: Yellow to Yellow = 0.4 ohms +/-20%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 The new 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 the new 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’’.
