Question

There is a spark at the electrodes but no ignition. A further check shows that the burner motor is not operating. Where should a voltage reading be taken to further troubleshoot the system?

a. Across terminals 15 and 2
b. Across terminals 3 and 8
c. Terminals 2 and 3
d. Across terminals 3 and 2

Answer 1

To troubleshoot the system, the student should take a voltage reading across terminals 2 and 3. It will help determine if there is a problem with the burner motor.

Step-by-step explanation:

The student should take a voltage reading across terminals 2 and 3 to further troubleshoot the system. In a series circuit, the voltage across each component is the same, so measuring the voltage at these terminals can help determine if there is a problem with the burner motor. If there is no voltage difference across these terminals, it indicates that the burner motor is not receiving the necessary voltage for operation.
