This circuit module is compatible with all the D3000 Base Unit options and introduces students to automotive electrical circuits through a wide range of practical activities.

Typical topic areas include:

• Fault Finding - The Basics
• Battery and Fuse
• Starter and Solenoid
• Horn and Relay
• Park, Tail and Headlamps
• Turn Signal and Hazard Warning Lights
• Brake and Backup Lights

Typical activities include:

• Investigate circuit faults as short. Open and resistance circuit faults.
• Identify the effects of short, open and resistance circuit faults.
• Identify the internal construction of the battery.
• Diagnose faults in the battery and fuse circuit.
• Recognize inertia, pre-engaged, axial and co-axial starter motors.
• Measure voltage, current and resistance in the starter and solenoid circuit.
• State how multi-horn circuits are electrically connected.
• Identify the difference between NO and NC relays.
• Construct a circuit diagram of the indicator signal and hazard circuit.
• Interpret the parking and headlamp circuit diagram.
• Identify applications for each of the bulb types used in the automotive industry
• Identify through taking measurements, live and switched live points of the reversing light circuit.
• Diagnose faults in the Brake and Reversing circuits.
