AUT108 Week 1 Quiz Ignition Systems

When the voltage reaches the point where current is flowing in the secondary circuit, the _______ drops to a much lower level, just sufficient enough to sustain current flow and the spark.

Select one:

• Reserve voltage

• Low voltage

• High voltage

• Required voltage

Which of the following does the ignition system use to convert relatively low-voltage and high-current flow into very high-voltage and very low-current flow?

Select one:

• Induction coil

• Ignition switch

• Ignition module

• Spark plugs

The original ignition system found in vehicles was the:

Select one:

• waste spark system.

• electronic ignition system.

• contact breaker points system.

• distributorless ignition system.

With the higher voltages that today's electronic ignition systems have to endure because of the increased spark plug gaps and leaner air fuel mixtures, the insulation material on the high-tension leads is now much ________ than in earlier models.

• Softer

• Thicker

• Lighter

• None of the above

The ________ connect the coil to the distributor cap center terminal and the distributor cap side terminals to the terminals on the top of the spark plugs.

Select one:

• High-tension leads

• Spark plugs

• Both A and B

• Neither A nor B

The primary winding of the ignition coil has approximately _______ turns of enameled copper wire.

Select one:

• A few hundred

• 1,000

• 15,000

• None of the above

Tech A states that in a contact breaker point ignition system, the number of lobes on the distributor shaft is equal to the number of cylinders. Tech B states that number of lobes is twice the number of cylinders. Who is correct?

Select one:

• Tech A

• Tech B

• Both A and B

• Neither A nor B

The vacuum advance mechanism controls ignition advance in relation to engine ________.

Select one:

• Load

• Temperature

• Speed

• MPH

________ is routed from the carburetor to a spring-loaded diaphragm housing attached to the distributor.

Select one:

• Current

• Voltage

• Vacuum

• Load

Select one:

• True

• False
