MAGNETO
(D-2000
SERIES).

DESCRIPTION
AND
PRINCIPLE
OF
OPERATION.
The
D-2031
magnetos
feature
two
electrically
independent
ignition
circuits
in one
housing.
A single
four
pole
rotor
provides
the
magnetic
energy
for
both
circuits.
This
magneto
uses
an
impulse
coupling
to
provide
reliable
ignition
to
engine
cranking
speed.
A
single
cam
operates
the
main
breakers
for
both
magneto
circuits.
Suppression
of
contact
point
arching
and
conducted
ratio
interference
is
accomplished
by
feed-thru
capacitors
which
are
mounted
in the
magneto
cover
which
forms
a part
of the
magneto
harness
assembly.
At
low
engine
cranking
speeds
the
impulse
coupling
automatically
retards
the
magneto
until
the engine
is also
at its
retard
firing
position.
The
spring
action
of
the
impulse
coupling
is
then
released
to
spin
the
rotating
magnet
and
produce
the spark
required
to
fire
the engine.
After
the
engine
starts,
the
impulse
coupling
flyweights
do
not
engage
due to
centrifugal
action.
The coupling
then
acts
as a straight
drive
and the
magneto
fires
at
the normal
firing
position
of the
engine.

INSPECTION
OF
MAGNETO.
After
the
first
50
hour
period
and
every
100
hours
thereafter,
the
magneto
ignition
system
should
be checked.
If engine
operating
troubles
develop
which
appear
to be
caused
by
the
ignition
system,
it is advisable
to
check
the spark
plug
and
wiring
first
before
working
on the
magneto.
Should
trouble
appear
definitely
associated
with
the
magneto,
the
most
effective
measure
is to
install
a
replacement
magneto
which
is known
to
be
in satisfactory
condition
and
send
the
suspected
unit to
the
overhaul
shop
for
rest and
repair.
Should
this
not
be possible,
a visual
inspection
of the
following
items
may
disclose
the
source
of trouble.
