• Non-resistor spark plugs in use
• Poor connection (spark plug cap to high tension lead)
• Poor connection (high tension lead to ignition coil)
• Fouled spark plug
• Faulty spark plug cap
• Poor grounds or connections in electrical box
• Faulty ignition coil
• Poor connections to Hall Effect sensors (trigger)
• Faulty Hall Effect sensor (trigger)
Symptoms: No spark or weak/intermittent spark on all cylinders.
• Non-resistor spark plugs in use
• Fouled spark plug
• Engine stop switch faulty (shorted)
• Low battery voltage / crank speed too low with spark plugs installed
• Wiring incorrect or disconnected
