ASE A6 Electrical Systems Practice Exam

A vehicle's engine is slow cranking. The battery has 12.6V and is in good condition. A voltage drop test is performed to test the starter circuit. Technician A says the test result above indicates there is excessive resistance in this circuit. Technician B says the ignition must be disabled and the starter cranked in order to perform this test. Who is correct?

• Technician A only
• Technician B only
• Both Technician A and B
• Neither Technician A nor B

The electrical symbol above is :

• A capacitor.
• A inductor.
• A diode.

An alternator suffers from low voltage output. The alternator outputs maximum voltage when full-fielded. Which of the following is MOST likely at fault?
