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.
