5. The ammeter should read less than 0.1 mA. If the
amperage is greater, there is a current draw on the
system that will discharge the battery.
Charging Voltage Test
1. Connect an engine tachometer to the spark plug
lead on the No. 1 (rear) cylinder.
2. Connect a 0-20 DC voltmeter to the battery ter-
minals as shown in
Figure 3
.
3. Start the engine and increase engine speed to ap-
proximately 5000 rpm. The measured voltage
should equal the charging voltage specified in
Ta-
ble 1
.
4. If the charging voltage is out of specification,
check the stator coil resistance as described in this
chapter.
STATOR
Resistance Test
Test the stator assembly at a minimum tempera-
ture of 20° C (68° F).
1. Remove the toolbox cover and the left side cover
as described in Chapter Fourteen.
2. Roll back the boot from the electrical cables.
3. Disconnect the three-pin stator connector (A,
Figure 4
) from its mate on the wiring harness.
4. Measure the stator coil resistance.
NOTE
In each of the following tests, connect
the ohmmeter’s positive lead to the
connector’s center terminal (A,
Fig-
ure 5
) and the ohmmeter’s negative
lead to the other terminal (B or C).
5. Measure the resistance between the center termi-
nal (A,
Figure 5
) and the left terminal (B) in the
stator side of the connector.
6. Measure the resistance between the center termi-
nal (A,
Figure 5
) and the right terminal (C) in the
stator side of the connector.
7. Replace the stator assembly if either resistance is
not within the range specified in
Table 1
.
8. Check the continuity between each terminal and
ground. There should be no continuity (infinite re-
sistance). Continuity between any stator wire and
ground indicates that either the stator or one of the
