THE ELECTRICAL SYSTEM
Within a self-study
Within one hour
No supplementary references are needed for this task.
In the previous lessons and tasks, we have discussed the characteristics of
the high mobility multi-purpose wheeled vehicle (HMMWV). We also discussed
the characteristics and operation of the 6.2 liter diesel engine, drive
train, suspension system, and the brake steering system.
The electrical system on any vehicle serves an indispensable purpose.
Without the electrical system, most vehicles could not be started, it would
be impossible to operate the vehicle at night since there would be no
external or internal lighting; additionally, there would be no way for the
operator to monitor vehicle operation such as speed, engine coolant, oil and
a multitude of other items that must be constantly checked to ensure correct
vehicle operation. In this lesson, the characteristics and operation of the
HMMWV electrical system will be discussed.
