DSL-206 Chap 19: Quiz Electrical Wiring and Diagrams

Technician A says that parallel wiring is a type of custom-made wiring harness that encloses multiple conductors into a single vinyl insulator covering. Technician B says that parallel wiring is often used for rear taillight wiring in trucks, buses, and trailer harnesses. Who is correct?

• a. Technician A

• b. Technician B

• c. Both Technician A and Technician B

• d. Neither Technician A nor Technician B

Technician A says that in most wiring diagrams, metric-sized wire is specified in centimeters. Technician B says that as the diameter of the wire

increases in the metric gauge standard, the gauge also increases. Who is correct?

• a. Technician A

• b. Technician B

• c. Both Technician A and Technician B

• d. Neither Technician A nor Technician B

A conductor 100 ft long with 0.5 ohms of resistance required to carry 10 amps of current in a 12-volt circuit sees a voltage drop of __________.

• a. 12 volts

• b. 7 volts

• c. 6 volts

• d. 5 volts

Why is multi-stranded wire better at conducting higher amounts of current with less resistance?

• a. Because it has an adhesive layer between the tubing and wire.

• b. Because it encloses multiple conductors into a single vinyl insulator covering.

• c. Because it has more surface area to conduct electron flow.

• d. Because current tracks that contain electrical components and conductors are situated between power and ground.

__________ wires become more resistant and heat up as amperage increases.

• a. Smaller

• b. Larger

• c. Thicker

• d. Thinner

What are the two main types of terminals used in harness connectors?

• a. Male and female

• b. Weather Pack and Metri-Pack

• c. Pull-to-seat and push-to-seat

• d. Bosch and Deutsch

Technician A says that pull-to-seat terminals are installed by inserting the wire through the connector cavity, crimping on a terminal, and then pulling

the terminal back into the connector cavity. Technician B says that push-to-seat terminals are inserted into the back of the connector cavity after the

terminal is crimped to the wire. Who is correct?

• a. Technician A

• b. Technician B

• c. Both Technician A and Technician B

• d. Neither Technician A nor Technician B

Which one of the following statements is NOT true about the Metri-Pack connector from Delphi?

• a. It is rated at 20 amps per pin at 16 volts DC

• b. Terminals have core wings that allow crimp-only connections.

• c. Terminals are flat and tin-plated.

• d. It is a pull-to-seat connector

__________ is used for terminal applications demanding high-reliability conducting with low-resistance and high-frequency electrical signals

• a. Copper

• b. Gold

• c. Silver

• d. Tin

What role does a latch or a lock play in a connector?

• a. Surrounds and protects the terminal area

• b. Prevents intrusion of dirt into the terminal area

• c. Prevents the connector from separating

• d. Provides resistance to failures caused by vibration and heating
