Current and Voltage Output Test
1. See Figure 7-19. Connect load tester.
a. Connect negative and positive leads to battery ter-
minals.
b. Place load tester induction pickup over positive reg-
ulator cable.
CAUTION
Do not leave any load switch turned on for more than 20
seconds or overheating and tester damage are possible.
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 for use in
TEST.
NOTE
Rider's habits may require output test at lower RPM.
Voltage Output Test
1. See Figure 7-19. After removing the load, read the load
tester voltage meter.
a. If voltage to the battery is not more than 15 VDC,
voltage output is within specifications. Investigate
other possible problems. See
b. If voltage is higher, regulator is not functioning prop-
erly or connections are loose or dirty.
Stator Check
1. Turn ignition key switch to OFF.
2. See Figure 7-20. Connect an ohmmeter.
a. Locate voltage regulator connector [46] near the oil
pump. Disconnect from alternator stator wiring.
b. Insert one ohmmeter lead into either stator socket.
c. Attach the other lead to a suitable ground.
3. Test for continuity with ohmmeter set on the RX1 scale.
a. A good stator will show no continuity (∞ ohms)
across either stator socket.
b. Any other reading indicates a grounded stator which
must be replaced.
4. See Figure 7-21. Remove ground lead. Insert lead into
the remaining stator socket.
5. Test for resistance with ohmmeter set on the RX1 scale.
a. Resistance across the stator sockets should be 0.2-
0.4 ohms.
b. If the resistance is lower, the stator is damaged and
must be replaced.
