iGNITION
TERMINAL
Test again by jumping the two large terminal studs. Hold the
screwdriver blade finnly between the studs. Do not allow
the
screwdriver blade to touch the solenoid or starter casing, this
would cause a short.
A
WARNING:
There will be arching
as
the full
starting current should be flowing thru the blade of
the screwdriver.
If the starter spins, the solenoid is faulty.
If the starter fails
to
spin, the motor is probably faulty.
Ifno arching occurred, there
is
no juice reaching the
solenoid.
NOTE: Starter motors are either inertia type or pre-engaged.
In the pre-engaged model, the solenoid also moves an arm
that engages the starter motor to the flywheel of the engine.
using a screwdriver to bypass the solenoid on such a starter
will run the motor without engaging the flywheel. Tum the
starter switch on to provide power to the solenoid. Hopefully
it will create enoughmagneticfieldfor the arm to move even
thaugh the contacts inside the solenoid are bad.
EMERGENCY START
Corrosion to the starter brushes andlor
the
solenoid contacts
can cause the sporadic problem of the engine starting one
time but not another. If corrosion is
the
problem, the starter
will need to be rebuilt
It is however, sometimes possible to get started by taping the
starter lightly with a small hammer.
With the battery switch off and no ignition,. tap lightly on the
starter/solenoid casing as shown, then to start the engine.
If that fails,
turn the
battery switch on and have a
member
turn the
iguition on and off rapidly as you tap again
with the hammer., This may loosen the brushes and allow
contact to start the engine. When you reach a repair facility,
the starter will need to be repaired.
