SERIES 60 ENGINE OPERATOR'S GUIDE
Item 19 – Oil Pressure
Under normal operation, oil pressure
is noted each time the engine is
started. In the event the equipment
has warning lights rather than pressure
indicators, the pressure should be
checked and recorded every 60,000
miles (96,000 km) for vehicle engines
or 600 hours for stationary and
industrial engines.
Item 20 – Battery-Charging
Alternator
Precautions must be taken when
working on or around the alternator.
The diodes and transistors in the
alternator circuit are very sensitive
and can be easily destroyed.
To avoid equipment damage, pay
attention to the following:
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.
Do not reverse battery
connections.
Never disconnect the battery
while the alternator is operating.
Disconnecting the battery can
result in damage to the battery
diodes. In applications which
have two (2) sets of batteries,
switching from one set to the
other while the engine is running
will momentarily disconnect the
batteries.
If a booster battery is to be used,
batteries must be connected
correctly (negative to negative,
positive to positive).
Never use a fast charger with the
batteries connected or as a booster
for battery output.
For information on the alternator
assembly, contact an authorized
Delco Remy
®
or Bosch
®
distributor,
depending on manufacturer.
