Known-Good Waveform
The 1972 Dodge Challenger 400ci V8 uses a conventional breaker point distributor system with mechanical advance curves. Engine timing is controlled by centrifugal and vacuum advance mechanisms, not electronic sensors.
Common Failure Patterns
No sensor present on this vehicle
Cause: Carbureted engine with points ignition - no crankshaft position sensor used
Diagnostic Tips
This vehicle uses points, condenser, and mechanical distributor. Check dwell angle (27-32 degrees) and initial timing (TDC-5° BTDC). For ignition diagnostics, scope the coil primary and secondary patterns instead.
