The Trooper™ Basic Installation and User’s Guide 7
5. Power and Ignition Harness/Fuses
The 20-foot Power and Ignition Harness for The Trooper™ Basic System uses
a pair of 18 AWG power wires to connect to the vehicle battery and a 22AWG
yellow wire to connect to an ignition switched circuit.
IMPORTANT: The Battery Power wires should be connected as close to the
battery as possible.
If there is a master battery switch in the battery compartment connected to the
battery’s negative (-) terminal, then the black Battery Power wire should be
connected after the switch. The red Battery Power wire should be connected to
the supplied in-line fuse, and then the fuse should be connected directly to the
battery’s positive (+) terminal.
There are two main reasons for connecting directly to the battery:
1) The battery acts as a very good filter for transients and surges on the vehicle
power lines.
2) The lines from the battery have a voltage drop across them because of
current drawn by lights, blowers, A/C units, etc. If the voltage drop is too
large, then the DVR will detect the low voltage and stop recording to protect
itself. If the voltage stays low for too long, the DVR will interpret this as
meaning the vehicle battery is drained and the DVR will shut down
completely.
IMPORTANT: The supplied in-line automotive fuse holders are for protecting the
Battery Positive wire (red) and the Ignition Trigger wire (yellow). Butt-splice
connectors are supplied to connect the fuse holders to their respective wires. The
Battery Positive fuse holder uses the 3A automotive blade fuse, and the Ignition
Trigger fuse holder uses the 1A automotive blade fuse.
