Textbook Problem

The firing lines on an oscilloscope pattern are all abnormally low. Technician A says that the problem is probably low coil output. Technician B says that the problem could be an overly lean air-fuel mixture. Who is correct?

a. Technician A

b. Technician B

c. Both A and B

d. Neither A nor B

To determine

The technician with correct approach.

Explanation

Given information:

The firing lines on an oscilloscope pattern are all abnormally low. Technician A says that the problem is probably low coil output. Technician B says that the problem could be an overly lean air-fuel mixture.

An oscilloscope is used to convert the electrical activity of an ignition system into a visual form. It is used to represent continuous voltage with time. The graph shows a pattern over a period. Technicians used these patterns to check the functioning of firing lines. Low coil output doesn’t affect the pattern on an oscilloscope...
