Page 3–13 Troubleshooting: Battery Charger Error and
Swap cutting reel motors between
cutting units. Replace and program
the motor if the fault moves to the new
position (contact an Authorized Toro
Distributor for assistance).
Inspect the harness connectors at
the cutting unit motor for damage,
corrosion, debris, and proper alignment
of the pins inside the connectors.
Test the connectors for 48V with the
engine shut off and the key in the On
position.
Test the power and ground wiring
resistance in the harness connectors.
Test the 48V bus Maxi blade fuse
under the left side cover.
Check the 2 pin, 48V bus connector of
the cutting unit motor.
Cycle the key switch.
Replace and program the motor
(contact an Authorized Toro Distributor
for assistance).
Check for mechanical resistance in
the cutting unit suspension making the
actuator work extra hard.
Replace and program the actuator
(contact an Authorized Toro Distributor
for assistance).
Cycle the key switch.
Use the InfoCenter to calibrate the
actuator.
