2. Test continuity of the alternator windings by setting
the multimeter to the ohms scale. Read all combinations
between the sky blue and white wires (criss–cross) on
the connector from the alternator.
A. Two measurements should be 0.1 ohms.
B. Two measurements should be O/L.
3. Check insulation resistance between lead wires and
alternator casing.
A. Make sure test lead makes good contact with the
alternator casing.
B. Resistance for each coil should be greater or
equal to 3 Megohms.
4. Place Functional Control Lever in NEUTRAL and
start engine.
5. Run engine so the alternator is running at 2365 rpm.
Read combinations between the sky blue and white
wires (criss–cross) on the connector from which conti-
nuity was found in step 2. Voltage across the connector
terminals should be about 39.4 VAC.
6. If the AC voltage output of the alternator is correct
and the DC current and voltage outputs are bad, replace
the voltage regulator. If the AC voltage output of the al-
ternator is bad, replace the alternator and retest the volt-
age regulator.
