In this video, an automotive technician demonstrates how to inspect, maintain, and replace secondary wires, spark plugs, distributors, ignition coils, electronic control units, and power train control modules. Ignition timing is also covered, and common problems involving all components are illustrated, with an emphasis on spark plugs (flashover, insulator cracks, fouling, incorrect gap, and incorrect spark duration) and distributors (carbon traces, burnt cap tower, pickup coil damage, and incorrect air gap in the crankshaft sensor). A viewable/printable instructor’s guide is available online. Correlates to National CTE Organizational Standards (including the provisions of the Perkins Act).
