5-14 3. In turn on each cap, touch a tester lead to each end of the spark-plug cap. B170 4. Spark-plug cap resistance must be between 4000- 6000 ohms. IGNITION SWITCH 1. Remove the main wiring harness connectors from the ignition switch. 2. Rotate the key to the OFF position. 3. The meter must read less than 1 ohm resistance between the ignition switch terminals. 4. Rotate the key to the RUN position. 5. The meter must read OL (infinite resistance). Testing Electrical Resistances (800/1000 cc Models) NOTE: Resistance tests of the engine electrical IGNITION COIL (Primary) 1. Disconnect the double wire plug from the ECU to the ignition coil. 2. Set the selector in the OHMS position. 3. Connect the red meter lead to the black/white lead; then connect the black meter lead to the white/blue lead. 4. Ignition coil primary resistance must be between 0.24-0.36 ohm. IGNITION COIL (Secondary) 1. Remove the spark-plug caps from the high ten- sion wires. 2. Set the selector in the OHMS position. 3. Connect the red meter lead to one high tension wire; then connect the black meter lead to the other high tension wire. AK050D 4. Ignition coil secondary resistance must be between 5040-7560 ohms. CHARGE COIL (1) 1. Disconnect the triple-wire plug from the main wir- ing harness to the magneto. 2. Set the selector in the OHMS position. 3. Connect the red meter lead to the black/red wire in the plug; then connect the black meter lead to the green/red wire in the plug. AK014 4. Charge coil (1) resistance must be between 7.20- 10.8 ohms. CHARGE COIL (2) 1. Disconnect the triple-wire plug from the ECU to the magneto. 2. Set the selector in the OHMS position. 3. Connect the red meter lead to the brown/white wire in the plug; then connect the black meter lead to the green/red wire in the plug. |
