Output Test
WHEN CHECKING ALTERNATOR COMPONENTS
MAKE TESTS IN THE FOLLOWING SEQUENCE:
Temporarily disconnect stator wire harness from
regulator-rectifier.
1. Insert RED test lead into V receptacle in meter.
2. Insert BLACK test lead into COM receptacle.
3. Rotate selector to V~ (AC VOLTS) position.
4. Attach RED test lead clip (1) to GREEN output
terminal (3), Fig. 24 .
5. Attach BLACK test lead clip (2) to engine
ground.
6. With the engine running at 3600 RPM , AC output
should be no less than :
•
28 Volts AC – 5 Amp System
•
40 Volts AC – 9 Amp System
7. If NO or LOW output is found, replace the stator.

Regulator-Rectifier Test
NOTE: The regulator-rectifier will not function
unless it is grounded to engine. Make sure
the regulator-rectifier is securely mounted
to the engine. When testing
regulator-rectifier for amperage output, a
12 volt battery with a minimum charge of 5
volts is required. There will be no output if
battery voltage is below 5 volts.
CAUTION: Connect test leads BEFORE starting
engine. Be sure connections are secure. If a
test lead vibrates loose while engine is
running, the regulator-rectifier may be
damaged.
Connect stator wire harness to regulator-rectifier.
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 RED DC output
terminal (3) on regulator-rectifier, Fig. 25 .

5. Attach BLACK test lead clip (2) to POSITIVE (+)
battery terminal.
6. Run the engine at 3600 RPM . The output
should be:
•
3-5 Amps – 5 Amp System
•
3-9 Amps – 9 Amp System
NOTE: The amperage produced depends on
battery voltage. If the battery is below
11
volts , the output reading would be 5 or 9
amps , depending upon the alternator
system being tested. The amperage will be
less at maximum battery voltage.
7. If NO or LOW output is found, be sure that
regulator-rectifier is grounded properly and all
connections are clean and secure. If there is still
NO or LOW output, replace the
regulator-rectifier.
10 & 16 Amp Regulated Alternator
The 10 or 16 amp regulated alternator system
provides AC current through two YELLOW output
leads to the regulator-rectifier. The regulator-rectifier
converts the AC current to DC and regulates current
to the battery. The charging rate varies with engine
RPM and temperature.
The stator and regulator-rectifier are the same for
the 10 and 16 amp systems. The system output is
determined by the flywheel magnet size.
