Using a small-diameter pinion gear, the starter motor rotates the engine through a __________ attached to the flywheel.

During the cranking process, the pinion of the starter motor engages with the __________.

Technician A says that the ratio between the flywheel ring gear and pinion gear is anywhere between 10:1 and 15:1 in gasoline engines. Technician B says that the higher cranking torque required for diesel engines uses 15:1 to 22:1, with 18:1 being the most common. Who is correct?

What is the electric motor classification where the field and armature windings are connected in parallel?

Which of the following statements is NOT true about DC series motors?

In series motors, the current flows through the __________, and then to the __________, before leaving through the __________.

When battery voltage is low, the starter uses __________ amperage to rotate.

__________ torque is produced at low speed because the motor draws the highest amperage.

What are the three main components, typically, of an armature?

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?

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 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 __________.

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

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

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

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?

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

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

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

What is a ladder logic?

Which of the following holds true for electronic control modules?

Conventional electrical systems are __________.

In a networked controlled system, switching on the wipers __________.

Technician A says that distributed control of the electrical system means a variety of modules shares control of the electrical system operation. Technician B says that distributed control of the electrical system means a variety of modules has direct point-to-point wiring connections. Who is correct?

FMVSS __________ is the standard for headlamp concealment devices.

Which of these are included in major exterior lighting circuits?

Any light on the exterior of the vehicle must have photometric certification for FMVSS __________ standards.

Technician A says that the FMVVS legislates standards for design and construction. Technician B says that legislated standards protect the public. Who is correct?

While discussing lighting circuits, Technician A says that the lamps facing rearward must emit red light. Technician B says that the lamps facing sideways and all turn signals must emit either amber or red light. Who is correct?

Technician A says that the mechanical ground switches are used to indicate low fluid levels, low air pressure warning systems, or power divider engagement locks. Technician B says that electronic switches are most commonly used for warning lights. Who is correct?

Technician A says pneumatic switches are the most common way warning lights are illuminated in today's vehicles. Technician B says warning lights provide easily understood information to alert the equipment operator to potentially dangerous operating conditions. Who is correct?

If gauges do not respond with a prove-out sequence when ignition is switched on, a possible cause could be __________.

Most gauges using stepper motors have __________ possible steps of positions between zero and full-scale deflection.

What type of gauge is not electrical because it depends on cables, air, or fluid pressure to operate?

Technician A states that safety interlock prevents unsafe accessory operation if any number of correct operating conditions are not met. Technician B states that safety hazards can be avoided with the use of a proper safety interlock. Who is correct?

Which of the following holds true for electrical system programming for accessories?

__________ allow(s) the customization of switch functions.
