Measuring the resistance of the primary winding of the ignition coil
Pic. 7.3. Measuring the resistance of the primary winding of the ignition coil
Connect the wire from the negative (–) 3 V power supply terminals to terminal 2 of the ignition coil. Then check the condition of the circuit with terminals 1 and 2 of the ignition coil with the positive wire disconnected and connected from terminal 3 of the ignition coil (+) power supply terminals (pic. 7.3).
Measuring the resistance of the secondary winding of the ignition coil
Pic. 7.4. Measuring the resistance of the secondary winding of the ignition coil
Measure the resistance between the high voltage terminal and the spark plug terminal of the ignition coil (pic. 7.4).
Rated value: approx. 12.1 kΩ.
