1. Avoid grounding the output terminal.
Grounding an alternator's output wire
or terminal (which is always hot,
regardless of whether or not the
engine is running) and accidentally
reversing the battery polarity will result
in equipment damage.
2. Do not reverse battery connections.
This can also cause damage.
CAUTION:
To avoid injury from battery explo-
sion or contact with battery acid,
work in a well-ventilated area,
wear protective clothing, and
avoid sparks or flames near the
battery. Always establish correct
polarity before connecting cables
to the battery or battery circuit. If
you come in contact with battery
acid:
Flush your skin with water.
Apply baking soda or lime to
help neutralize the acid.
Flush your eyes with water.
Get medical attention immedi-
ately.
3. Never disconnect the battery while
the alternator is operating. Dis-
connecting the battery can result in
damage to the alternator diodes. In
applications which have two sets of
batteries, switching from one set to
the other while the engine is running
will momentarily disconnect the bat-
teries. This can result in equipment
damage.
4. If a booster battery is to be used, bat-
teries must be connected correctly
(negative to negative, positive to posi-
tive) to avoid equipment damage.
5. Never use a fast charger with the bat-
teries connected or as a booster for
battery output.
For information on the alternator assem-
bly, contact an authorized Delco-Remy
or Bosch ® distributor, depending on
manufacturer.
Item 21 — Engine and Transmission

tightened and/or repaired as necessary.
Item 22 — Crankcase Pressure
The crankcase pressure should be
checked and recorded every 600 hours
or 60,000 miles (96,000 km).
Item 23 — Fan Hub
If the fan bearing hub assembly has a
grease fitting, use a hand grease gun
