DESCRIPTION
SYMPTOM
Controller has detected an over temperature
condition in the traction motor or
power bridge.
Traction and hydraulic systems will not operate.
Probable Causes and Test Procedures
6.
Check for shorts with truck frame (Continued).
NOTE:
Excessive current draw will cause a component to heat up and this is usually caused by shorts in
the system allowing current to follow paths that are not intended. Sometimes excessive current draw can
be caused by mechanical malfunctions such as worn bearings, misaligned parts, improper lubrication,
and brake adjustments. Other factors include operator misuse such as overloading the truck and pushing
loads.
The condition of the battery can contribute greatly to excessive current draw. When the battery charge
and voltage are low, more current is needed to perform the same task. Since the power required to move
a load is Power = Volts × Amperage, as the battery voltage goes down, the amperage must increase to
maintain power.
