Question

two techs are discussing a compression test. technician a says that the throttle plate should be held wide open during the test. technician b says that the vehicles battery should be fully charged. who is correct?
select one:
a. technician a
b. technician b
c. both a and b
d. neither a nor b

Explanation:

During a compression test, holding the throttle plate wide open allows maximum air - fuel mixture into the cylinders for an accurate test. A fully - charged battery is necessary to ensure the engine cranks at the proper speed (which is crucial for an accurate compression reading). So both Technician A and Technician B are correct.

Answer:

C. Both A and B
