A starter cranks for a while, then whines. Technician A says that the starter solenoid may be bad. Technician B says that the starter drive may be bad. Which technician is correct?

a. Technician A only
b. Technician B only
c. Both Technicians A and B
d. Neither Technician A nor B


b. Technician B only
Technician B is correct because a worn starter drive will cause the starter motor to spin and not rotate the engine flywheel. Technician A is not correct because if the starter is rotating, the solenoid has to be working because the drive pinion is forced to mesh with the flywheel before current flows through the solenoid to the starter motor. Answers c and d are not correct because Technician B only is correct.
