DC Motor Troubleshooting

See “DC Motors” on page5-15.

AC Motor Troubleshooting

See “AC Motors” on page5-20.

Conduct a partial inspection of the motor during scheduled maintenance. If the truck is operated in a severe or caustic environment or is used in an extended duty cycle application, inspect the motor more frequently.

Set up and rigidly adhere to a strict inspection schedule to obtain the maximum efficiency from the electrical equipment.

Each partial inspection of the motor must include:

1.Inspect the brushes for wear and for correct contact with the commutator. Record the level of wear on the brushes. This history provides an indication of whether a brush must be changed or if it can wait until the next inspection. Refer to Table 7-6 on page7-54 for acceptable brush length.

NOTE: Overloading a unit is ultimately reflected in the motor and brush wear; therefore, you must take this into account when considering brush replacement.
