In the '97 E-450 horn diagram:
the clockspring is coil of wire used to build up a magnetic field
the clockspring is used to keep time accurate in the vehicle clock
the clockspring 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, 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 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
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
A dashed line around a component symbol indicates:
the symbols inside are part of a control module
a complete component; what is shown is all inclusive
an incomplete component; there is more that is not shown
the component is part of a module that grounds through its case
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
On the van horn diagram, there are optional circuits paths based on functions equipped on the vehicle
True
False
wiring diagrams only show one circuit path
"S104" would represent a _______ in a diagram.
connection
split
splice
slice
