Current and Voltage Output Test
1. See Figure 7-22. Connect load tester.
a. Connect negative and positive leads to battery ter-
minals.
b. Place load tester induction pickup over positive reg-
ulator cable.
2. Run the engine at 2000 RPM. Increase the load as
required to obtain a constant 13.0 VDC.
3. The current output should be 19-23 amps. Make note of
measurement.
Voltage Output Test
See Figure 7-22. After removing the load, read the load tester
voltage meter. Voltage to the battery must not be more than
15 VDC. If voltage is higher, regulator is not functioning prop-
erly or connections are loose or dirty.

CAUTION
Do not leave any load switch turned on for more than 20
seconds or overheating and tester damage are possible.
Stator Check
1. Turn ignition to LOCK.
2. Disconnect stator wiring from voltage regulator wiring at
connector [P17].
3. See Figure 7-23. Connect an ohmmeter on the RX1
scale between crankcase and either stator socket. Test
for continuity.
a.
A good stator will show no continuity (
∞
ohms)
across either test point.
b. Any other reading indicates a grounded stator which
must be replaced.
4. See Figure 7-24. Check the resistance using an ohmme-
ter set on the RX1 scale.
a. Resistance across the stator sockets or pins should
be 0.2-0.4 ohms.
b. If the resistance is lower, the stator is damaged and
must be replaced.
