2.4.2 Routing of power cable
1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the
customer, vehicle manufacturer, agent or supplier.
Note:
In this event, exercise extreme caution throughout the installation and fit the fuse
only when the installation is complete.
2. The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric
“Weather-Pack” connector (DC power Connector, see Figure 4).
Figure 4 - DC Power Connector
The DC Power connector has:
• At position “A”, the smaller red switch-sense wire (commonly to ignition)
• At position “B”, the blue ground wire
• At position “C”, a larger red B+ DC power wire (MUST be unswitched)
3. Place this connector at GeminiG3 unit’s radio power input location. Do not connect at this time.
See paragraph 2.6, “Completing the physical installation”.
4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usu-
ally
as close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal
part(s). Secure the wires at several locations along their length.
Caution:
Use proper crimping tool. Common pliers are NOT acceptable.
Warning:
The DC Power lead must be unswitched
5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force
the metal contacts onto the wires.
6. Repeat the step above for connecting the red DC power lead.
7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle
end of the battery ground cable.
If the negative cable is connected directly to the battery negative terminal, it
should be fused in case of failure of the vehicle’s ground cable.
Ensure tight and secure connections.
8. Fasten the fuse holder and leads.
9. Carefully route the “A” wire to where the connection will be made for switch sensing.
• Connect to “Ignition” if you wish to have GeminiG3 unit turning ON and OFF dependent on
the vehicle’s ignition key.
• Connect to “Accessory” if you wish GeminiG3 unit to be available when the engine is not
running, but still dependent on the ignition key.
• Connect to a user-supplied control switch.
