EBS01036 EBS01038 Is the spark plug cap OK? YES NO Replace the spark plug cap. Replace the ignition coil. 9 - 13 IGNITION SYSTEM ELEC – + ELEC – + 5. Spark plug cap resistance • Remove the spark plug cap from the spark plug lead. • Connect the pocket tester (Ω × 1k) to the spark plug cap as shown. • Measure the spark plug cap resistance. Spark plug cap resistance 10.0 kΩ at 20 °C (68 °F) 6. Ignition coil resistance • Disconnect the ignition coil connectors from the ignition coil terminals. • Connect the pocket tester (Ω × 1) to the ignition coil as shown. Positive tester probe → red/black lead terminal 1 Negative tester probe → orange lead terminal 2 • Measure the primary coil resistance.
Primary coil resistance 3.4 ~ 4.6 Ω at 20 °C (68 °F) • Connect the pocket tester (Ω × 1k) to the ignition coil as shown. Positive tester probe → red/black lead terminal 1 Negative tester probe → spark plug lead 2 • Measure the secondary coil resistance. Secondary coil resistance 10.4 ~ 15.6 kΩ at 20 °C (68 °F) • Is the ignition coil OK? YES NO
