How to Adjust the Generator
Voltage Regulator
The voltage regulator regulates the output voltage
of the generator. A properly adjusted voltage
regulator is essential to good generator
performance and service life. A defective or
improperly adjusted voltage regulator could result
in component damage.
Note: Be sure the batteries are fully charged
before performing this procedure.
1 Remove the engine pivot plate latch retainer.
2 Open the engine pivot plate latch and swing
the engine out away from the machine to
access the generator.
3 Connect the positive lead of a voltmeter to the
pos terminal on the generator and the
negative lead of the voltmeter to the neg
terminal on the generator.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
4 Start the engine from the ground controls and
move the rpm select toggle switch to the
maintained high idle position. Check the
voltage on the generator.
Result: The voltage should be 54V DC.
5 If the voltage reading is not 54V DC, insert a
small flat blade screwdriver into the
potentiometer located inside of the generator.
Use the access hole on the back of the
generator labeled volt adj.
Component damage hazard.
Be sure that the screwdriver is
properly inserted into the
potentiometer or the generator
and/or voltage regulator may
become damaged.
6 Carefully adjust the potentiometer to obtain a
54V DC voltage reading. Turn the
potentiometer clockwise to increase the
voltage or counterclockwise to decrease the
voltage. Do not rotate the potentiometer past
the internal stops.
Component damage hazard.
The voltage regulator inside the
generator will become
damaged if the potentiometer is
rotated past the internal stops.
Note: The maximum range of motion of the
potentiometer on the voltage regulator is 280° and
the maximum allowed torque is 5 oz-in / 0.035 Nm.
