ELECTRICAL NOTE: If there are any significant variations in ohm readings between the three legs it is an indication that
it idleWhile holding the engine at specified RPM, separately measure the voltage across each leg' of the stator by connecting
the meter leads to the wires leading from the alternator (Y1 to Y2, Y1 to Y3, Y2 to Y3)Refer to the following table for approximate
AC Voltage readings according to RPMTest each leg at the specified RPM in the tableExample: The alternator current output
reading should be approximately 18 VAC at 1300 RPM between each leg'NOTE: If one or more of the stator leg output AC voltage
varies significantly from the specified value, the stator may need to be replacedRPM Reading 1300 3000 5000 AC Voltage (VAC)
