Description
What is a Starter Motor?
What are the symptoms of a bad starter motor: When starting a car with a fully charged battery, there is a single click or nothing happens at all. The starter motor doesn't run, even though there is a 12-Volt power at the starter control terminal.
Another symptom is when the starter motor runs, but fails to turn over the engine. Often, this might cause a loud screeching noise when starting the car. Of course, this could also be caused by damaged teeth on the ring gear of the flex plate or flywheel.
Starter solenoid
Starter solenoidStarter solenoid.A typical starter solenoid has one small connector for the starter control wire (the white connector in the photo) and two large terminals: one for the positive battery cable and the other for the thick wire that powers the starter motor itself.
The starter solenoid works as a powerful electric relay. When activated, through the control terminal, the solenoid closes the hi-current electric circuit and sends the battery power to the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh with the ring gear of the engine flexplate or flywheel.
How
the
starting
system
works:
When
you
turn
the
ignition
key
to
the
START
position,
or
press
the
START
button,
if
the
transmission
is
in
Park
or
Neutral,
the
battery
voltage
goes
through
the
starter
control
circuit
and
activates
the
starter
solenoid.
The
starter
solenoid
powers
the
starter
motor.
At
the
same
time,
the
starter
solenoid
pushes
the
starter
gear
forward
to
mesh
it
with
the
engine
flywheel
(flexplate
in
an
automatic
transmission).
The
flywheel
is
attached
to
the
engine
crankshaft.
The
starter
motor
spins,
turning
over
the
engine
crankshaft
allowing
the
engine
to
start.
In
cars
with
a
push
button
start,
the
system
disengages
the
starter
as
soon
as
the
engine
starts
running.
