1. TROUBLE SHOOTING AND REPA IR
0 Engine does not turn ov er when th e s tarter
switch button is depre ssed.
l . The click of the starter re l ay is not heard when
the starter switch button is depressed.
11 I Probable cause: Poor contact at the battery
terminal due to looseness or corrosion. Cor-
rective ac ti on : Inspect the terminal and if loose,
tighten and apply a coat of grease; if corroded,
remove the battery, pour hot water on the
terminal to
disconnect and then clean before
reconnecting the lead wire, and then apply a.
coat of grea se to prev ent corrosion . Check
the
EB terminal particularl y.
1 21 Pr ob a bl e cause : Batter y electroly te level low.
Check the ele ctrolyt e level and if be l ow the
l
ower l ev el mark, a dd distilled water to the
upper l ev el.
!31 Check the ele ct ro lyte for prope r specific gravity.
(4) When the st arter switch button is making poor
cont act, disassemble the switch and clean.
If the tr o uble is not due to the causes above,
take it to a specialist. In most cases, the cause is
due to worn brushes or dirty commutator . A brush
worn to less than 1/ 3 should be rep l aced with a
genuine
part . W hen dir ty commut ator is the cause,
polish
with a fine sandpaper and clean the carbon
from the mica insulator as shown in Fig. 5.4 (Fig. 5- 4)

l . Fi rst, check to assure that the swi tc h is on and
then perform the inspectio ·n by the following pro-
c edure .
(
a) Connect one lead of the starter magnetic switch
to the EB t er minal of the battery and the ot h er
lead to the ground and if an energizing click
sound is
not heard :
( l I The plunger coil is defective due to a broken
wire, therefore , replace the coil.
However, if an energ izing click is heard in the
starter relay, the defect is a poor contact in the
starter sw itch but ton or the con tact plate within
the magn
et ic switch, therefore, disassemble the
part and clean the contact areas . (Fi g. 5-5)
