When looking at the current waveform of a fuel injector solenoid or an ignition coil primary winding, current that builds too quickly to the saturation level suggests what type of fault?

A. Open winding

B. Shorted winding

C. Circuit has excessive resistance on the insulated side

D. Circuit has excessive resistance on the ground side

When looking at a current waveform of a fuel pump motor, the waveform is seen to go to ground twice for each rotation of the motor.

What does this indicate?

A. Open winding

B. Shorted winding

C. Physical binding due to worn bushings

D. Poor contact between the brushes and the commutator segments
