Lesson 1 • Ignition System Diagnosis

Applies a no-spark diagnostic tree covering coil, trigger, module, and wiring faults. Students restore spark delivery and confirm correct timing after repair.

Lesson 2 • Ignition Timing and Advance Systems

Covers mechanical advance, vacuum advance, and ECU-controlled timing maps. Students verify timing with a timing light and interpret advance curves.

Lesson 3 • Trigger Sensors and Signal Generation

Explains reluctor-based and Hall-effect trigger sensors that signal the ignition control module. Students measure sensor output waveforms and compare to specifications.

Lesson 4 • Ignition Coils and Spark Plugs

Covers primary and secondary winding resistance, saturation time, and spark plug heat range selection. Students test coils and inspect plugs to assess combustion quality.

Lesson 1 • Headlight Systems and Beam Adjustment

Covers halogen, HID, and LED headlight technologies, including bulb replacement and aim adjustment. Students set beam height to meet safety requirements.

Lesson 2 • Tail, Brake, and Running Light Circuits

Traces dual-filament and LED tail/brake circuits, including brake switch integration. Students diagnose open and short circuits in rear lighting.

Lesson 3 • Instrument Cluster and Warning Lights

Covers analogue gauge senders, digital cluster communication, and warning indicator logic. Students diagnose inaccurate gauge readings and false warning lights.

Lesson 4 • Accessory Circuit Installation and Protection

Teaches proper fusing, relay-switched wiring, and load calculation for added accessories. Students install accessories without compromising factory circuit integrity.

Lesson 1 • EFI System Architecture

Maps the ECU, sensors, actuators, and communication networks in a modern EFI system. Students identify each node's role in closed-loop fuel control.

Lesson 2 • Fuel Pump and Pressure Circuit Diagnosis

Covers fuel pump prime cycle, pressure specification, and volume flow testing. Students diagnose hard-start and lean-surge faults caused by fuel delivery issues.

Lesson 3 • Engine Sensors and Signal Interpretation

Covers TPS, MAP, IAT, ECT, and O2 sensor operation and expected signal ranges. Students measure sensor outputs and compare them to specification tables.

Lesson 4 • Fuel Injector Testing and Service

Teaches injector resistance, balance flow testing, and pulse-width measurement. Students identify clogged or leaking injectors and perform cleaning or replacement.

Lesson 1 • Intermittent Fault Diagnosis Strategies

Covers thermal cycling, vibration simulation, and data logging to capture faults that disappear on the bench. Students build a repeatable process for elusive electrical problems.

Lesson 2 • Digital Multimeter Advanced Functions

Covers min/max capture, duty cycle, frequency, and diode test modes beyond basic voltage measurement. Students apply each mode to real motorcycle circuit faults.

Lesson 3 • Voltage Drop Testing Under Load

Applies dynamic voltage drop testing to identify high-resistance connections in power and ground circuits. Students locate corroded terminals and undersized wiring causing intermittent faults.

Lesson 4 • Waveform Analysis for Sensors and Actuators

Interprets CKP, CMP, injector, and coil primary waveforms to identify timing and mechanical faults. Students correlate waveform anomalies to specific component failures.

Lesson 1 • Wire Repair and Splicing Techniques

Covers solder-and-shrink, crimp splice, and butt connector methods with correct wire gauge matching. Students perform repairs that meet factory tensile and conductivity standards.

Lesson 2 • Grounding System Inspection and Repair

Maps chassis ground points, engine ground straps, and ECU ground circuits critical to system stability. Students measure ground resistance and restore corroded ground connections.

Lesson 3 • Connector Service and Terminal Repair

Explains connector disassembly, terminal extraction, and pin replacement for OEM multi-pin connectors. Students restore connector sealing and locking function after terminal service.

Lesson 4 • Full-System Integration and Final Verification

Applies a systematic power-up sequence and functional test checklist after major electrical repairs. Students confirm all subsystems operate correctly before returning the motorcycle to service.
