TEST PROCEDURE
1. Start the engine and run it at high idle (3650
RPM).
2. Set the voltmeter for AC volts and place one
meter probe on each of the two outside leads
that attach to the engine voltage regulator. See
Figure F.5 for location. Check for 42-52 VAC at
the voltage regulator.
3. If the AC voltage is low or not present, the
engine flywheel alternator may be faulty. This is
an engine problem; consult your local engine
repair facility.
4. If the voltage reading is correct, then check the
output of the voltage regulator to determine the
charging voltage for the battery.
Run the
engine at high idle (3650 RPM).
Set the volt-
meter for DC volts and place one meter probe
on the middle lead and one probe on the green
ground wire connected to the voltage regulator.
See Figure F.5 for location.
Check for 13-15
VDC.
5. If the DC voltage reading is incorrect or not pre-
sent, the voltage regulator may be faulty.
Replace the entire voltage regulator module.
6. If the DC voltage reading is correct, check the
associated wiring and circuitry. See the
