ELECTRICAL TROUBL•J-TRACIJXG
Starter (Pinion locl,i11g in Flywheel
6ear)
When the starter pinion is engaged with the flywheel gear and either
fails to turn the engine or does not disengage when the engine commences
to run, it will not be possible, in the case of the former, to turn the engine
with the starting handle. Remove the three bolts securing the starter to the
engine back-plate, withdraw the starter assembly and "free" the pinion.
Probable causes : (1) Worn starter pinion, pinion spiral sleeve or
flywheel gear;
(2)
worn or dirty starter brushes (see Starter, Pages
33
and
39);
·
(3)
partly discharged battery;
(4)
loose or dirty battery
terminals; or
(5)
armature shaft bent due to previous pinion seizure.
NOTE: Do not, in any circumstances, attempt to" Free" the starter
by forcing the starting handle, as this will result in serious damage.
Starter (failure of Pinion to engage
witli Flgwheel 6ear)
Probable causes :
(1)
Partly discharged battery ;
(2)
battery
terminals loose or dirty;
(3)
partially seized starter pinion (remove, clean
and lubricate with thin oil);
(4)
starter brushes worn or dirty (see Starte
r
,
Pages
33
and
39) ;
or
(5)
loose connections on starter motor.
Wiring Harness
Causes of electrical failure may be divided into two main sections:
(1) Failure of electrical equipment to operate due to a wire breakage.
(2) A
short circuit resulting in a high discharge being shown on the ammeter
and the battery becoming rapidly discharged.
Trouble in these categories may take place between the battery and
switches or on a particular circuit ; in the case of the latter the trouble
will
reveal itself only when the controlling switch is " on." In the event
of either type of trouble, locate in the following manner :
(1)
Determine
the section which is affected;
(2)
examine the wiring connections (the
wires may he frayed or loose); and (3) check the wiring for damage.
