Question

when performing a power balance test, the cylinder being tested must be disabled. technician a says to disconnect the fuel injector for the cylinder being tested. technician b says to disable the spark for the cylinder being tested. who is correct? select one: a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

In a power balance test, to disable a cylinder, both disconnecting the fuel injector (as Technician A suggests) and disabling the spark (as Technician B suggests) are valid methods. Disconnecting the fuel injector stops fuel supply, and disabling the spark prevents ignition. Both actions effectively disable the cylinder for the test.

Answer:

c. Both A and B
