Total questions: 20
Worksheet time: 10mins
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
Technician A says that heat-shrink tubing does not provide effective protection to a spliced electrical connection. Technician B says that spliced
connections need protection against water wicking. 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 is not advisable to increase wiring longevity?
a. Cover wiring and harness in a protective loom
b. Route wiring away from heat sources and moving parts
c. Secure wire with clips and plastic ties
d. Occasionally rinse with water
Crimp connectors must be used with __________ to make the repair permanent
a. Double-walled shrink tube
b. Barrel-type crimping pliers
c. Single-walled shrink tube
d. Shrink-type connectors
What is water wicking?
a. Movement of water beneath wiring insulation
b. Measures taken to prevent water intrusion and condensation
c. The insulation's ability to resist intrusion by a liquid
d. Corrosion of wire due to water
Why is soldering wires together better than just twisting?
a. Because it provides additional abrasion resistance
b. Because it provides protection against water wicking
c. Because it provides a strong-mechanical and low-electrical resistance
d. Because it provides the best seal for a spliced electrical connection
Technician A says that isometric diagrams are used to locate current flow within a system. Technician B says that schematic diagrams are line drawings that explain how a system works by using symbols and pictures. Who is correct?
a. Technician A
b. Technician B
c. Both Technician A and Technician B
d. Neither Technician A nor Technician B
__________ diagrams are representative of all wiring diagrams in use today
a. DIN
b. VF
c. Block
d. Isometric
In __________ diagrams, current paths are arranged to show signal or mechanical action from left to right and or top to bottom.
a. Schematic
b. Pictorial
c. Isometric
d. Linear
Relays require a signal from a(n) __________ to activate.
a. Outside source
b. Component
c. Designator J
d. Transistor
The purpose of the terminal designation system is to __________.
a. Enable connection verification of wiring to components for repair
b. Allow the technician to follow current flow through the component
c. Allow the technician to break the complex symbol down into smaller components
d. Find the continuation of a conductor on another page or diagram
