No-spark diagnosis (fast path)

If you have zero spark, don’t shotgun parts. Isolate the system in a clean order.

These steps apply to most off-road singles (Blaster / Tri-Moto / Tri-Z / Tecate 3).

• Disable kill switch circuit temporarily (test-only).
• Use a known-good plug and confirm good grounding to the head.
• Check coil primary/secondary continuity and connector condition.
• Measure stator exciter and pickup (manual specs).
• Inspect flywheel key and flywheel torque (signal can disappear if it slips).
