Operation Source Voltage
The
Maestro
™
is designed to connect
to and is powered by 12 to 24 VDC
electrical systems. It comes supplied
with a 23 ft. heavy duty power cable and
a Y-connector with 2 battery clips.
Connecting To The Vehicle’s Battery
(Voltage Source)
Connect the red clip to the positive ter-
minal of the vehicle’s battery source and
the black clip to the negative or ground
terminal. The
Maestro
™
start-up tone will
sound.
Auxiliary Ground Lead
The auxiliary ground lead provides
ground to circuits and components that
are not already connected to ground.
It also serves as the negative lead for
resistance testing. To test the auxiliary
ground lead, contact the probe tip and
the auxiliary ground lead together. The
Green LED should illuminate. This shows
that the auxiliary ground lead is working
properly. If the green LED does not illu-
minate, check the replaceable 20 amp
fuse in the auxiliary ground lead. The
fuse is for protection in the event the
ground lead inadvertantly contacts the
positive voltage.
LED Flashlight
Flashlight is a standard feature on the
Maestro
™
. The two bright white LEDs
are always ON making it possible to see
under dashboards and in dark areas.
