Connecting the Control Head Power Cable to the Boat
A 6' (2 m) long power cable is included to supply power to the control head. You may shorten or
lengthen the cable using 18 gauge multi-stranded copper wire.
CAUTION:
Some boats have 24 or 36 Volt electric systems, but the control head MUST be connected to a
12 VDC power supply.
The control head power cable can be connected to the electrical system of the boat at one of
two places: a fuse panel usually located near the console, or directly to the battery.
NOTE:
Make sure that the power cable is disconnected from the control head at the beginning of this
procedure.
NOTE:
Humminbird® is not responsible for over-voltage or over-current failures. The control head must have
adequate protection through the proper selection and installation of a 3 Amp fuse.
NOTE:
In order to minimize the potential for interference with other marine electronics, a separate power
source (such as a second battery) may be necessary.
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not
included) that match the terminal on the fuse panel. Attach the black wire to
ground (-), and the red wire to positive (+) 12 VDC power. Install a 3 Amp fuse
(not included) for protection of the unit. Humminbird® is not responsible for
over-voltage of over-current failures.

.
1b. If you need to wire the control head directly to a battery, obtain and install
an inline fuse holder and a 3 Amp fuse (not included) for the protection of the
unit. Humminbird® is not responsible for overvoltage or over-current failures.
NOTE: Your unit will detect when your battery voltage is too low or too high, and will display
either Input Voltage Low or Input Voltage High messages if these limits are exceeded. If you
turn the Low Battery Alarm on using the Alarms Main Menu, your unit will use your settings.
If you do not turn the Low Battery Alarm on, the unit will use these limits: 7.5 to 7.9 VDC for
the low end, and 21 to 21.2 VDC for the high end.
