Remove "IGNITION COIL".
Measure the resistance between "Power" terminal and "Control" terminal of "IGNITION COIL".[1st coil resistance]
Measure the resistance between "Power" terminal and "High-voltage" terminal of "IGNITION COIL".[2nd coil resistance]
■ Specification :
1st coil resistance | 0.558 Ω ~ 0.682 Ω (20℃, 68℉) |
2nd coil resistance | 5.95 ㏀ ~ 8.05 ㏀ (20℃, 68℉) |
Are the 1st coil resistance and the 2nd coil resistance normal?
