coil with a rope or an equivalent.
11. Crank the engine for approximately 3 seconds to see if sparking occurs between spark plug and the grounded metal portion.
CAUTION:
• The discharge voltage becomes 20 kV or higher. There-fore, always stay away from the spark plug and ignition
coil at least 50 cm (19.7 in) during the inspection.
• Leaving a space of more than 17mm (0.66 in) may damage the ignition coil.
