48V Precharge
Failure
Motor/Generator
controller
This fault is reported
when a minimum
voltage of 38 Vdc was
not achieved on the
48V precharge circuit.
1) Disconnect all 5 cutting reel
motors and attempt to start the
engine.
2) If the engine starts, connect 1
cutting reel motor at a time with
the key off until connecting a
reel motor causes the fault.
3) Replace the faulty cutting reel
motor.
4) If all cutting reel motors are
good, test the 48 V logic power
and ground wiring in the main
harness.
64
Temperature
Sensor Failure
Motor/Generator
controller
This fault is reported
when the field effect
transistor (FET) and
motor temperature
sensors fail inside the
motor/generator.
Replace the motor generator
controller.
65
Speed Stall –
Cutting Reel Motor
1
Motor/Generator
controller
This fault is reported
when the cutting reel
motor on cutting unit 1
stalls due to heavy
cutting conditions or
because of a cutting
unit malfunction.
• When any individual cutting
reel motor is shut off due to
a fault, the TEC-5002 shuts
off the other 4 cutting reel
motors.
• You can only swap cutting
unit 1 with cutting units 3 or
5.
1) Inspect the cutting unit for any
debris clogging the reel.
2) Check the bedknife adjustment
and inspect the condition of the
reel.
3) Swap cutting reel motors
between cutting units.
4) Replace faulty cutting unit
motors.
5) Swap cutting units.
6) Inspect the cutting reel motor
wiring.
7) Measure 48 Vdc power in
connectors P46 and P47.
8) Test for power and ground in
connectors P46 and P47.
9) Test the CAN bus wiring in
connector P46.
