Power Options

J umpStart: Provides High
cold-cranking amps to assist in
starting your engine (12 Vdc and 24
Vdc). This option uses power from
your tug's batteries to assist your
aircraft's batteries when starting
your plane. Note: Even when the
tug is off, the JumpStart panel is
live! (Although the readouts won't
show until the tug is on.)
GPU: The Ground Power Unit is
used to power your avionics and
other lower power demand systems
in your aircraft from the standard
110 Vac wall connection. You have
28.5 Vdc at 25/50 Amps. Note: Do
not use the GPU to power air condi-
tioning or pitot tubes. Warning: bat-
tery damage is possible—the GPU
should not be used to charge either
the tugs or the aircraft's batteries!
JumpStart + Boost: Press the
silver button to the right of the
JumpStart JumpStart panel, and the
tug gives you thirty minutes (from
the time you pushed the button.)
with over 28 Volts from the GPU
and all those amps from the batter-
ies providing power to the plane.
The disadvantage of using only the
JumpStart option is that you are us-
ing the tugs batteries that discharge
with time, and some planes require
over 28 Volts before they can rec-
ognize the external power source.
With the JumpStart plus Boost, you
can combine both sources of power
for an excellent source of current
at the correct voltage to start your
plane.
