DC Alternator
The DC alternator provides DC current for charging
a 12 volt battery. The current from the alternator is
unregulated and is rated at
3 amps . The output rises
from 2 amps @ 2400 RPM , to 3 amps @ 3600 RPM .

Output Test
NOTE: The battery MUST be in good condition to
perform this test.
WHEN CHECKING ALTERNATOR COM-
PONENTS, PERFORM THE TEST IN THE
FOLLOWING SEQUENCE:
1. Insert RED test lead into 10A receptacle in
meter.
2. Insert BLACK test lead into COM receptacle.
3. Rotate selector to A== (DC amps) position.
4. Attach RED test lead clip (1) to DC output
terminal, Fig. 13 .
5. Attach BLACK test lead clip to POSITIVE (+)
battery terminal (2).
6. With engine running at 3600 RPM , output should
be 2 - 4 amps DC.
NOTE: The output will vary with the battery voltage.
If the battery is at maximum voltage the out-
put will be approximately 2 amps.
7. If NO or LOW output is found, test diode.

Diode Test
In the DIODE TEST position, the meter will display
the forward voltage drop across the diode(s). If the
voltage drop is
less than 0.7 volts , the meter will
BEEP once and display the voltage drop. A
CONTINUOUS TONE indicates CONTINUITY
(shorted diode). An INCOMPLETE CIRCUIT (open
diode) is displayed as
OL .
1. Insert RED test lead (1) into V receptacle in
meter.
2. Insert BLACK test lead (2) into COM receptacle
in meter.
3. Rotate selector to +

)) (DIODE TEST) position.
4. Attach RED test lead clip to point A and BLACK
test lead clip to the stator output lead (3), Fig. 14 .
(It may be necessary to pierce the wire with a pin
as shown.)
a. If meter BEEPS once , diode is OK.
b. If meter makes a CONTINUOUS TONE ,
diode is defective (shorted). Replace diode.
c. If meter displays OL proceed to step 5.
5. Reverse test leads.
a. If meter BEEPS once , diode is installed
backwards. Replace diode.
b. If meter still displays OL , diode is open.
Replace diode.
6. If diode tests OK, check stator for bare wires or
other obvious defects. If bad or grounded leads
are not visible, replace the stator.
