Intro to Wiring

What is a clock spring ?

• the clock spring is coil of wire used to build up a magnetic field

• the clock spring is used to keep time accurate in the vehicle clock

• the clock spring is spiraled ribbon wire that allows the steering wheel to rotate freely without damaging wiring

• The clock spring is a one-way connection

A relay,

• 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 an 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

A fuse

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

• A 10 amp rated fuse switches current flow

• A 10 amp rated fuse is for circuit protection

A window motor can roll a window up and down due to:

• current polarity changes when the window rocker switch is pushed

• a special transmission attached to the window motor gear

• the activation of separate "up" and "down" motors

• the window regulator being on a circular track

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

• True

• False

• Depends who you ask

What is this

• Speaker

• Tweater

• Clockspring

Using ohms law what is the resistance if the current draw is 3 amps with the battery voltage at 12 volts

• 2

• 6

• 3

• 4
