a) Operating Voltage Source
The PPH is designed for use in 12 to 48 VDC electrical sys-
tems and comes supplied with a 20 ft., 10-gauge coax cable
and 2 heavy-duty battery hook-up clips.
b) Connecting to the Vehicle’s Battery
(Voltage Source)
Connect the red clip to the positive terminal of the vehicles
battery source and the black clip to negative or ground. The
PPH start-up tone will sound and the indicator light on the Y-
Connector with Battery Clips will illuminate. This tells you that
the Hook is connected correctly and the internal fuse of the
Y-battery-clip-connector is working properly.
c) Y-Connector with Battery Clips
The Y-Connector with Battery Clips has a safety fuse built into
it. The built-in fuse will blow in the event the 10-gauge coax
power cable gets clamped or pinched in a door or hood caus-
ing a short circuit.
Note: If the Y-Connector with Battery Clips does not light when
properly connected to the voltage source, you probably have a
damaged 10 gauge coax power cable. It is recommended that
the cable be inspected and tested before replacing a new Y-
Connector with Battery Clips.
Contact your distributor or Power Probe, Inc. for a replacement.
d) 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 on the display
should light. This shows that the auxiliary ground lead is work-
ing properly.
If the green LED does not illuminate, check the replaceable 25
amp fuse in the auxiliary ground lead. The fuse is a protection
in the event the lead is inadvertently contacted with battery
positive.
e) Flashlight
Flashlight is a standard feature on the PPH. The bright LED
Flashlight is always ON making it possible to probe under
dashboards and in dark areas.
f) Sleep Mode
The PPH goes to sleep after 10 minutes of inactivity and you
will see SLEEPING in the display. The Flashlight and the LCD
backlight will turn off. To wake it up, just press any button or
contact the probe tip to a circuit.
