Critical Note: Electrical parts are not "one size fits all." There are four common variations of this stator (#151-46, #151-187, #151-188, and #151-296). Electrical parts are not returnable.
Verification Tip: Compare your existing plug to the photos—this model specifically uses a 3-pin female plug combined with 2 single leads.
Pro Tip: Always check your Voltage Regulator when replacing a stator; a failed regulator is the #1 cause of "burnt" stator coils!
