Auto1405- Electronic Accessories (Basics)

What is the most common failure point of a frozen wiper system?

• wiper transmission

• wiper blades

• wiper motor

• dual motors

A relay, such as the one in the horn diagram:

• uses a high current circuit to control a low current circuit

• uses a switch to activate a control coil to make the horn sound

• uses a control coil to close a switch using electromagnetism

• amplifies 12V energy to high voltage to sound the horn

The ground symbol at the end of the horn circuit:

• indicates where the circuit begins

• is always a wired connection leading to the negative side of the battery

• indicates a conductive connection to the negative side of the battery

• indicates one of the wires that drags on the ground while driving to complete power flow

The two "wavy" symbols in the center of the image indicate:

• fuses to allow the circuit to bear more than 10 amps of current flow

• 10 amp rated switches used to control current flow

• 10 amp rated fuses for circuit protection

• single-pole curved switches for improved conductor contact during operation

The circuit on the "hot" side of the low beam filament is:

• Circuit C121, Dark Brown with a Lime Green Stripe

• Circuit 1205, Black

• Circuit 1056, Dark Blue with a Light Green Stripe

• Circuit C121, Black

Electrical loads should consume all (most) of the voltage in a single-load circuit:

• True

• False

• Depends who you ask

"S104" would represent a _______ in a diagram.

• connection

• split

• splice

• slice

What is the minimum number of wires required for a washer pump to function?

• 4

• 3

• 2

How many LED light bulbs are required for a single headlamp assembly?

• One

• Multiple

Which 2 wiper arm system does not rely on the use of a linkage between pivots?

• conventional

• dual motor

• rear wiper

• spring tension
