Ignition coil testing is being discussed. Technician A uses an ohmmeter to measure primary and secondary resistance. Technician B uses an oscilloscope and a test spark plug to measure maximum coil output voltage. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct in their methods for testing an ignition coil. Technician A's use of an ohmmeter to measure primary and secondary resistance is a common practice for assessing coil condition. Technician B's use of an oscilloscope and a test spark plug to measure maximum coil output voltage is also a valid method for evaluating the performance of the ignition coil.
