Pin 6’s role extends beyond simple activation—it’s a mediator between the engine’s command and the spark’s execution.Wiring errors manifest in several predictable—but dangerous—forms:

• Incorrect Pin Assignment: Mixing up Pin 6 with a neighboring terminal—say, ground instead of signal—can ground the trigger voltage, silencing the ignition trigger without triggering a code.
• Loose or Corroded Contacts: Even a fraction of a loose connection introduces intermittent resistance, leading to voltage dips that confuse the CDI’s threshold sensors.
• Poor Shielding and EMI: Faulty grounding allows electromagnetic noise to couple into the signal line, causing erratic pulses that either stall the engine or cause premature ignition.
• Overheating Terminals: Pin 6 runs hot under load; a poor connection overheats, triggering thermal cutoff or degrading solder joints, compounding failure risk.
