Exam 18: Starting and Motor Systems

Technician A says permanent magnet starter motors are more robust than electromagnetic field type motors and can better withstand being dropped. Technician B says permanent magnet motors can produce more torque using less electric current. Who is correct?

Technician A says the purpose of the solenoid is to engage the starter pinion into the flywheel's ring gear. Technician B says the solenoid energizes the starter motor by closing the electrical circuit from the battery to the motor. Who is correct?

What is the purpose of field coils and pole shoes?

All positive engagement starters use a(n)____________________ in series between the battery and the starter motor.

Most starter motors have two to six brushes.

An engine cranks slowly. Technician A says a possible cause of the problem is low resistance in the starter circuit connections. Technician B says a possible cause is an open in the starter field coil circuit. Who is correct?

When performing a cranking current test: if a remote starter switch cannot be used, the _____ system must be disabled.

Describe some important safety precautions that should be followed while testing the starter.

The part of the armature that the brushes ride on is called the ____________________.

Why does proper starter operation depend on good battery cables and connectors?

Which of the following is NOT part of the starter motor circuit?

Some starters use planetary gearsets for gear reduction.

The field coils in the starter motor are connected in ______.

Nearly all starter system current testers (VAT)use an ____________________type ammeter to measure current draw.

The starter motor converts electric current into torque or twisting force through the interaction of magnetic fields.

The usual minimum cranking voltage specification is ______ volts.

Which of the following tests would be performed to check for high resistance in the positive battery cable?

The starter circuit requires strong voltage, but actual current flow is low.

The field coils connect in series with the armature windings through the starter ____________________.

The pull-in winding and hold-in winding are part of the _____.
