NORMAL
PROCEDURES
PA-28-181,
ARCHER
II
NOTE
For all normal operations using the PEP
jumper cables, the master switch should be
OFF, but it is possible to use the ship’s battery
in parallel by turning the master switch ON.
This will give longer cranking capabilities, but
will not increase the amperage.
CAUTION
Care should be exercised because if the ship’s
battery has been depleted, the external power
supply can be reduced to the level of the ship’s
battery. This can be tested by turning the
master switch ON momentarily while the
starter is engaged. If cranking speed increases,
the ship’s battery is at a higher level than the
external power supply.
