104
Over Current
Disable – CRM 5
Cutting Reel
Motor Controller
Cutting reel motor 5
has detected excessive
current draw and has
been disabled.
Check the InfoCenter for fault
69 (Speed Stall—CRM 5) or
fault 74 (High Temp Warning—
CRM 5), as an overheated
cutting reel motor or a cutting
reel motor stall could be a
contributing factor to a fault 104.
1) Swap cutting reel motors
between cutting units. Replace
the motor if the fault moves to
the new position.
2) Inspect main harness
connectors P44 and P45 at
cutting reel motor 5 for damage,
corrosion, debris, and proper
alignment of the pins inside the
connectors.
3) Test connectors P44 and P45
for 48V with the engine off and
the key in the ON position.
4) Test the power and ground
wiring resistance in main
harness connectors P44 and
P45.
111
Internal Regulator
Overvolt –
Motor/Generator
Motor/Generator
Controller
Excessive voltage
occurred at the
motor/generator’s 15
Vdc internal regulator,
and disabled the
motor/generator.
This fault can only be triggered
by a failure of the internal
motor/generator controller.
Such a failure would allow
voltage levels beyond
engineering specifications to
exist in the 48 Vdc circuitry.
Replace the motor/generator
controller.
