and
After
Since the alternator and electronic voltage regulator are de-
signed for use on only one polarity system, the following
precautionary measures must
be observed when working on
the charging circuit, or serious damage to the electrical
equipment will result:
1. When installing a battery, make certain that the ground
polarity of the battery and the ground polarity of the
alternator are the same.
2. When connecting a booster battery, be sure to connect
the negative battery terminals together and the positive
battery terminals together.
3. When using a battery charger, connect the positive lead
of the charger to the positive battery terminal and the
negative lead of the charger to the negative battery
terminal.
4. Do not operate an alternator on open circuit. Be sure all
circuit connections are secure.
5. Do not short across or ground any of the terminals on
the alternator or electronic voltage regulator.
6. Do not attempt to polarize an alternator.
MAGNETOS
Ordinarily, the magnetos will require only occasional
adjustment, lubrication, and breaker point replacement. This
work should be done
by a BEECHCRAFT Aero or Aviation
Center or International Distributor or Dealer.
WARNING
To be safe,
treat
the magnetos as
hotwhenever
a
switch
lead is disconnected at any point;
they
do not have an internal automatic
grounding
device. Otherwise, all spark plug leads should
be disconnected or the cable
outlet
plate on
the
rear of the magneto should be removed.
