Exam 16: General Electrical System Diagnostics and Service

When connecting a conventional ammeter to a circuit, _____.

When using a DMM to test resistance, the red lead is connected to the A jack.

When using an inductive current probe adapter on a DMM, _____.

Technician A uses a splice clip while soldering two wires together. Technician B twists the wire strands of the wire ends together before soldering. Who is correct?

What are the three classifications of electrical problems?

A beeping noise coming from the DMM when the function selector is set to ohms indicates that the circuit has ____________________.

Technician A says uses an ohmmeter to measure resistance of a component. Technician B uses a voltmeter to measure voltage drop. Who is correct?

A potentiometer [type of variable resistor] can be tested with all the following tools EXCEPT:

Explain how you would bench test a relay (the relay is removed from the vehicle).

A voltmeter is connected in ____________________ with the circuit.

All the following are lab scope adjustments EXCEPT:

What is the best tool to use to find the cause of an intermittent problem in a low-voltage DC circuit?

A technician is checking a circuit with excessive resistance. The current flow through the circuit should be 10 amps, but a check with an ammeter measures only 6 amps. The technician measures a voltage drop of 1.0 volts across the switch terminals when the circuit is turned on. What is the resistance of the switch?

A wiring diagram shows the actual position of parts on a vehicle.
