DESCRIPTION

The

essentially
of

in

circuits

incorporating
tran

sistors

These
transistors
int

and

admit

current
flow

to
the
alternator

rotor

coil
thus

maintaining
its

output

at
a
constant
value
Unlike
in
a

an
electron

employing
transistors
is

These

are

In

should

This
is

an

easy
and
effective

trouble

shooting
procedure
since
some

changes
in

oil
condition
are
often

linked
with

developed
troubles
For
instance

Lack
of
oil
causes
defective

opera

tion

by

making
the
clutches
and

brakes

slip
resulting
in

severe
wear

This
is

because
the
oil

pump
sucks

air

causing
oil

foaming
thus

rapidly

deteriorating
the
oil

quality
and

pro

ducing
sludge
and
varnish

Excessive
oil
is
also
bad
because
of

oil

foaming
caused

by
the

gears
stirring

up
the
oil

During

high
speed
driving

excessive
oil
in

the
transmission

often

hlows
