The Electrical Power simulator allows the student to experiment and to troubleshoot the electrical power systems in a car under normal and malfunctioning conditions. The instructor can insert twenty-five active faults.
Experiments and troubleshooting exercises, promoting safe and efficient electrical diagnostic procedures, include:
- Understanding battery and power cables
|
- Detection and repair of Batter malfunctions: battery discharged,
high resistance in ground cable, corroded negative and positive
battery terminals
|
- Operation and function of the alternator and voltage regulator
|
- Detection and repair of Starter malfunctions: high resistance in
starter cable, open starter and solenoid windings, shorted solenoid
harness, open electrical window breaker
|
- Understanding the starter system and power distribution
|
- Detection and repair of Fuse, Link and Component malfunctions:
open fusible link M, open charge indicator lamp, ignition switch
terminal 5 and 11, open gear switch and fusible link J
|
- Understanding the role of fuses and fusible links
|
- Detection and repair of Alternator malfunctions: open and shorted
stator winding, worn brushes, open and shorted rotor winding, bad
diode assembly, voltage regulator, and loose belt
