Answer: Technician A
Explanation: The major cause of solenoid clicking in cars is a dead or low battery. That should be the first point of check when a car clicks or starts to develop a hard start suddenly. The battery which plays an integral role in the ignition process of vehicles can sometimes run low and maybe unable to create enough charge to power the engine.
In the case of a solenoid clicking the battery should be carefully checked either to be recharged or changed if faulty.
