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.
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.
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.
