screwdriver blade firmly between the studs. Do not allow the
screwdriver blade
to
touch the solenoid or starter casing, this
wonld cause a short.

WARNING:
There will be arching as the full
starting current should be "owing thru the blade of
the screwdriver.
Iftbe starter spins, the solenoid is faulty.
If the
starter
fails
to
spin, the motor is probably fanlty.
If no arching occurred, there is no juice reaching the
solenoid.
NOTE:
Stalter nwtors are either inertia type or pre·engaged.
In the pre-engaged nwdel, the solelwid also nwves an am!
that engages the starler motor to the flywheel of the engine.
uoing a screwdriver to bypass the soleJwid on such a starler
will run the nwtor witTrout engaging the flywheel. Turn the
starler switch on to provide power to the soleJwid. Hopefully
it will create enough magnetic field for the ann to nwve even
tTwugh the contacts inside the solenoid are bad.

the starter brushes andlor the solenoid contacts
can cause the sporadic problem of the engine starting one
