35.6. With the regulator / rectifier disconnected, it is
also possible to check the stator output:
See Figure 35.6.
• Start the engine, and set the throttle to maintain
3,600 RPM.
• Touch the probes of a DVOM set to read A.C.
voltage to the female spade terminals on the
ends of the white wires in the harness plug that
connects to the regulator / rectifier.
• Output of a good stator should be greater than
28 volts.
35.7. With the engine turned-off, it is possible to check
the stator for an open condition:
See Figure 35.7.

• With the DVOM set to read Ohms, insert the
probes into the female spade terminals on the
ends of the white wires in the harness plug that
connects to the regulator / rectifier.
• If the reading is infinity or O.L., the stator wind-
ings are open, and it should be replaced.
35.8. With the engine turned-off, it is possible to check
the stator for a shorted condition:
See Figure 35.8.
• With the DVOM set to read Ohms, insert one
probe into one of the female spade terminals on
the ends of the white wires in the harness plug
that connects to the regulator / rectifier. Touch
the other probe to ground.
• Repeat for the second white wire.
35.9. If either test produces a measurement other than
infinity or O.L., the stator is shorted, and it
should be replaced.
