STARTER

MOTOR

[DESCRIPTION

irhe

starter

is

a

new

type,

small,

light-weight

and

is

called a

N.gh-speed

intemal-reduction

starter.

The

pinion

shaft

is

separate

from

the

motor

shaft;

the

pinion

slides

only

on

the

binion

shaft.

A reduction

gear

is

installed

between

the

motor

~haft

and

a pinion

shaft.

The pinion

sliding

part is

not

pxposed outside the starter

so

that

the

pinion

may

slide

smoothly without

becoming

fouled

with

dust

and

grease.

The

botor

shaft

is

supported

at

both

ends

on

ball

bearings.

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

,\he

ground wire

connections

on

the

engine

block.

tro

check

the

wiring,

try cranking the starter for a

few

~econds,

never

more

than

10

seconds

at

a

time,

tilen

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

temlinal stud

on

the

start solenoid

and

the

engine block

(ground).

If

yon read 12 volts, the starter

is

fanIly.

IGNITION

TERMINAL

~""'---I(M)

TERMINAL

To

test

the

ignition

circuit, locate 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 fanIt lies with the ignition

circnit.

If

the solenoid clicks but nothing happens, the

starter

motor is fanIty.

SOLENOID

IGNITION

-~

If

nothing happens

at

all, the solenoid is not gettiog

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

NO

flammable

solvents

or

materials

stored

nearby.
