PIPER

SIX
SERVICE
MANUAL
Located
on the
instrument
panel
are
two circuit
breakers
marked
"alternator";
one of
which
is
marked
"output"
and the
other
"field."
The
output
circuit
breaker
is 60
amperes
and
its
purpose
is to
protect
the
alternator
and
electrical
system
from
overload.
The
field
circuit
breaker
for the
voltage
regulator
and
field wiring
protection
is 5 amperes.
If
either
of
these
breakers
trip, it
will result
in
a complete
failure
of power
from
the generating
system.
After
a one or
two minute
cool-down,
they
can be reset
manually.
If
tripping
recurs,
holding
the breakers
down will
not prevent
their continued
tripping,
and
indicates
a breakdown
of
wiring
or equipment
in the generator
circuit.
Unlike
previous
systems,
the ammeter
does
not indicate
battery
discharge,
but displays
the
load
in amperes
placed
on the
generating
system.
With
all
electrical
equipment
off
(except
master),
the
ammeter
will
indicate
the
amount
of
charging
current
demanded
by
the
battery.
This
amount
will
vary, depending
on the
percentage
of
charge
in the battery
at the
time.
As the
battery becomes
charged,
the
amount
of current
displayed
on the ammeter
will
reduce
to approximately
two
amperes.
The
amount
of current
shown
on
the ammeter
will
tell
immediately
whether
or not
the alternator
system
is operating
normally,
if
the following
principles
are kept
in
mind.
