11. Manually start the unit and measure AC voltage
across Wire #11A and Wire #22A. A minimum of
60VAC should be measured.
The AC voltage measured across Wire #2 and Wire #6 should
be higher than the AC Voltage measured across Wire #11A
and Wire #22A.
Refer to Figure 21 when performing the following test. There
is one DC Amperage test to perform. The exact amperage
readings may vary depending on ambient temperature,
battery voltage, meter calibration, etc.
1. Set meter to measure DC Amperage.
2. Connect the meter in series between battery positive
( + ) and wire #4. Refer to the operation/instruction
manual for the meter you are using for correct test
lead locations and meter settings.
3. Connect the meter in series between the 12V battery
negative ( - ) and Wire #1.
4. Manually start the unit and measure DC Amperage.
Reading should be 1.0 - 1.5 Amps.

5. Disconnect the battery from Wire #1 and Wire #4.
6. Restore wiring connections to the circuit breaker and
the AVR.
7. Analyze test results as follows:
• If all readings are within the spec, the alternator is
good and the voltage regulator is suspect.
• If amperage reading is within the range, and one
or more of the voltage readings are low, the stator
is suspect.
• High amperage indicates a short. Verify battery
voltage, wiring, and connections. Repair as
necessary, then retest. If the reading is still high,
replace the rotor.
• Low on no amperage indicates an open. Verify
the meter’s fuse is good and check the battery
voltage, wiring, and connections. Repair as
necessary, then retest. If reading is still low,
replace the rotor.
