                STATOR OUTPUT TEST                                   2. Measure the resistance value of each of the stator
                Three tests can be performed using a multimeter to       legs to ground: Y1 to Ground, Y2 to Ground, Y3 to
                determine the condition of the stator (alternator).      Ground.
                                                                                           NOTE

                                                                         leading from the alternator (Y1 to Y2, Y1 to Y3, Y2 to
                                                                         Y3).

                1. Measure the resistance value of each of the three
                   stator legs: Y1 to Y2, Y1 to Y3, and Y2 to Y3. Each    RPM READING           AC VOLTAGE

                 If there are any significant variations in ohm's readings
                between the three legs; it is an indication that one of the
                        three stator legs maybe weak or failed.
