Output Test
WHEN CHECKING THE ALTERNATOR
COMPONENTS, PERFORM THE TEST IN THE
FOLLOWING SEQUENCE:
Temporarily disconnect stator wire harness from
regulator-rectifier.
1.
Insert RED test lead into VΩ receptacle in meter.
2.
Insert BLACK test lead into COM receptacle.
3.
Rotate selector to V~ (AC VOLTS) position.
CAUTION
Attach meter test leads to the AC output
terminals (YELLOW wires) in the connector
BEFORE starting the engine. If the stator
is grounded (defective) and the meter test
leads contact the center DC output pin (RED
wire) in the connector, arcing could occur,
damaging the wiring.
4.
Attach RED (2) and BLACK (1) test lead probes
to the YELLOW wire (4) AC output terminals
(6), of the connector (3), as shown in Figure 36.
(Meter test clip leads may be attached to either
AC output terminal).

5.
If NO or LOW output is found check for bare
wires or other defects. If shorted leads are not
visible, replace the stator.
6.
With the engine running at 3600 RPM output
should be no less than 26 Volts.
DC Output Charging Wire Test
A simple test can be used to test the DC output
charging wire circuit. If a wiring problem exists it can
be corrected before testing regulator-rectifier.
Leave stator wire harness disconnected from
regulator-rectifier. Equipment key switch must be in
OFF position.
1.
Insert RED test lead into VΩ receptacle in meter.
2.
Insert BLACK test lead into COM receptacle.
3.
Rotate selector to V= = (DC volts) position.
4.
Attach RED test lead probe (2) to the RED wire
(5) DC output terminal (7), of the connector
(Figure 36).
5.
Attach BLACK test lead probe (1) to negative
battery terminal.
6.
Turn equipment key switch to ON position.
Meter should display BATTERY VOLTAGE.
7.
If meter does not display voltage, check for blown
fuse or broken or shorted wire.
