Wiring the GHC 10 to Power and to the CCU Cable
With the GHC 10 power/data cable, wire the GHC 10 to power and to the yellow CCu signal wire on the CCu cable. Optionally, you
can wire the GHC 10 power/data cable to a NMEA 0183-compatible GPS device to use waypoint and route information with the GHP 10V,
although a NMEA 2000-compatible GPS device is preferred.
To wire the GHC 10 to power:
1. Route the GHC 10 power/data cable to the boat battery.
2. Connect the red (+ or positive) wire to the positive voltage terminal. (If you use the fuse block on the boat, route the positive connection
through the fuse.)
3. Connect the black (- or ground) wire to the negative voltage terminal.
4. Install or check the AGC/3AG – 1 A fuse (on the fuse block or in the in-line holder).
5. Connect the power/data cable to the GHC 10.
Notes:
• The replacement fuse is an AGC/3AG – 1 A fuse.
• If it is necessary to extend the power wires, use 18 AWG wire.
• If your boat has an electrical system, you might be able to wire the GHC 10 directly to an unused holder on your current fuse block. If you
are using the fuse block, remove the in-line fuse holder supplied with the GHC 10.
Caution: The GHC 10 maximum input voltage is 32 Vdc. Do not exceed this voltage, because this can damage the GHC 10 and void the warranty.
note: During a typical installation, use only the red, black, and yellow wires. The other wires are used for NMEA 0183 connections, and do not have
to be connected for normal operation of the GHC 10. For information on connecting to a NMEA 0183-compatible GPS device, see
To wire the yellow CCU signal wire from the GHC 10 power/data cable to the CCU cable:
1. Route the GHC 10 power/data cable to the bare end of the color-coded wires from the CCU cable. If the cable is not long enough, extend
the yellow CCU signal wire with 22 AWG wire.
2. Connect the yellow CCU signal wire from the GHC 10 power/data cable to the yellow wire on the CCU cable.
If you install multiple GHC 10 units and want to turn the GHP 10V autopilot system on with any of the installed GHC 10 units, connect all of
the yellow CCU signal wires from the GHC 10 units to the yellow wire on the CCU cable.
3. Solder and cover all bare-wire connections.
note: The yellow CCU signal wire must be connected from the GHC 10 power/data cable to the CCU cable, or else the GHP 10V autopilot system
will not power on with the GHC 10.
Connecting the GHC 10 to a NMEA 2000 Network
Connect the GHC 10 to the CCU through your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network on your
boat, you will need to create one. Optionally, you can connect a NMEA 2000-compatible GPS device to your NMEA 2000 network to use
waypoint and route information with the GHP 10V. For more information on NMEA 2000, visit www.garmin.com.
