STARTER 
MOTOR 
DESCRIPTION 
The starter 
is 
a 
new 
type, 
small, 
light-weight 
and 
is 
called a 
high-speed internal-reduction 
starter. 
The pinion shaft 
is 
separate 
from 
the 
motor shaft; 
the 
pinion 
slides 
only 
on 
the 
pinion 
shaft. 
A reduction gear 
is 
installed between 
the 
motor 
shaft 
and 
a pinion 
shaft. 
The pinion sliding part 
is 
not 
exposed outside 
the 
starter 
so 
that 
the 
pinion 
may 
slide 
smoothly without becoming 
fouled 
with 
dust 
and 
grease. 
The 
motor shaft 
is 
supported at both 
ends 
on 
ball bearings. The 
lever 
mechanism, 
switch and overrunning clutch inner circuit 
are 
identical 
to 
conventional 
ones.

TROUBLESHOOTING 
SOLENOID 
A 
WARNING: 
The 
following 
emergency 
starting 
procedures 
must 
not 
be 
used 
with 
gasoline 
engines. 
Sparks 
could 
cause 
an 
explosion 
and 
fire. 
Prior 
to 
testing, 
make 
certain 
the 
ships 
batteries 
are 
at 
full 
charge and that 
the 
starting system wiring connections 
(terminals) 
are 
clean 
and 
tight. 
Pay 
particular attention 
to 
the 
ground 
wire 
connections 
on 
the 
engine 
block. 
To 
check the wiring, try cranking 
the 
starter for a 
few 
seconds, never 
more 
than 
10 
seconds 
at a 
time, 
then 
run 
your 
hand 
along 
the 
wires 
and 
terminals looking 
for 
warm 
spots 
that indicate resistance. Repair or replace 
any 
trouble 
spots. 
Using a 
multimeter, 
test 
the 
voltage between the positive 
terminal stud 
on 
the 
start solenoid 
and 
the 
engine block 
(ground). 
If 
you read 12 volts, the starter 
is 
faulty. 
SOLENOID 
IGNITION 
TERMINAL 
To 
test 
the 
ignition circuit, 
lol.:ate 
the 
ignition(s) terminal (it 
is 
one 
of 
the 
small terminal studs 
and 
is 
wired 
to 
the 
ignition 
circuit). 
Use a screwdriver, don't touch 
the 
blade, 
to 
jump 
from 
that ignition terminal 
to 
the positive battery connection 
terminal 
on 
the 
solenoid. 
If 
the starter cranks, the fault lies with the ignition 
circuit. 
If 
the solenoid clicks 
but 
nothing happens, the starter 
motor 
is probably faulty.

If 
nothing happens 
at 
all, the solenoid is not getting 
current.. Check 
the 
battery isolation switch 
and 
inspect 
the 
wiring 
connections. 
it 
is 
also 
possible that 
the 
solenoid 
is 
defective. 
·  · 
A 
WARNING: 
There 
will 
be 
arching 
and 
sparks 
will 
fly 
when 
jumping 
terminals. 
Be 
certain 
the 
engine 
space 
is 
free 
of 
potentially 
explosive 
fumes, 
especially 
gasoline, 
and 
that 
there 
are 
I!Jl 
flammable 
solvents 
or 
materials 
stored 
nearby.
