Exam 18: Starting and Motor Systems

Technician A checks a starter's field coils for opens by connecting an ohmmeter between the coil's power feed wire and the field coil brush lead. Technician B checks a starter's field coil for a short to ground by connecting an ohmmeter from the field coil brush lead and the starter housing. Who is correct?

What is counter EMF ?

When the starter spins but does NOT crank the engine, which of the following may be a cause?

What device pushes the starter pinion gear into mesh with the ring gear when the ignition switch is in the start position?

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

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

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

The maximum voltage drop for the insulated circuit [battery positive to starter solenoid] is typically about _____ volt.

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

Pinion gear to flywheel ring gear clearance is being discussed. Technician A says if there is too much clearance, there will be a high-pitched noise after the engine starts. Technician B says if there is too little clearance, there will be a high-pitched noise while the starter is cranking the engine. Who is correct?

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

Some starters use ____________________ between the starter and the mounting pad to allow for proper clearance between the drive pinion gear and the flywheel ring gear.

Technician A says the starter solenoid mounts directly on top of the starter motor. Technician B says the starter solenoid pushes the starter drive pinion into mesh with the flywheel teeth. Who is correct?

The first step in removing a starter from a vehicle is __________________________.

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

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?

When a cranking voltage test is performed, the ignition system must be disabled.

Most starter motors have two to six brushes.

If flywheel ring gear teeth are worn, the ring gear should be ____________________.

Nearly all starter system current testers [VAT] use an ____________________type ammeter to measure current draw.
