Trouble shooting
If the battery turns extremely slow or not at all, the cause may
lie in the battery, wiring or the starter The lights are a very
convenient tool for tracing the cause of the trouble.
Light method
The use of this method, of course, assumes that the lights
are functioning normally.
(1) Lights are dim
Probable cause: Low battery. faulty contact at one of
the connections, faulty wiring. If the battery remains
discharged because of a malfunction in the charging
system, it should be corrected before charging the
battery to prevent the problem from reoccurring.
(2) With battery fully charged:
a) Symptom. Lights do not light
Probable cause: Battery terminal not properly
connected.
b) Symptom: Lights become extremely dim when
cranking the engine and starter slows down or
stops.
Probable causes.
Bad engine (rotational resistance too great)
Starter does not turn satisfactorily
Armature shaft bent
Worn bushing
Pole core screw loose
Field coil grounded or insulator short circuited
Armature coil grounded or insulator short-circuited
c) Lights are bright Out starter does not I urn or hums
very slowly.
Probable causes.
Starter terminal not connected properly
Solenoid switch not making contact
Solenoid not working (coil grounded or insulator short-
circuited)
Faulty starter switch contact
Insufficient brush contact
Dirty or worn commutator

Precautions in care and handling of starter motor
(1) The starting motor must be installed properly for the
starter pinion to mesh with the engine ring gear as
should. If the ring gear and pinion do not mesh properly,
the pinion and starter housing may be damaged and in
extreme cases, the starter may not even turn.
(2) If the starter switch is turned on and the engine turns,
but will not start, the cause is probably in the fuel
system. Check the fuel lines and correct as necessary.
(3) In attempting to start an engine, never use the starting
motor for more than 30 seconds at a time without a
pause to let is cool down. The starting motor heats up
very rapidly when used and if it is used continuously for
more than 30 seconds the solder may melt from the
armature or the coil or lead wires may melt. Also, the
battery will be discharged to such a degree and wont
have sufficient power for another attempt at starting. A
good rule to follow is to crank for 10 seconds and pause
for 10 seconds. Repeat until the engine starts.
(4)
If the starting motor is too far forward, the pinion will not
mesh properly with the ring gear and cause rapid pinion
wear. Adjust for proper mesh.
(5) Do not turn the starter switch while the engine is
running. If this is done, the pinion gear will contact the
ring gear, which is turning with the full force of the
engine which may cause a broken pinion, bent shaft,
broken housing, etc.
