Auto power wiring option, Fuel kit wiring

Auto power wiring option

Black wire: Connect this to the negative battery terminal.

Red wire: Connect this to the positive battery terminal after the main switch. Fit a 2 Amp fuse as shown.

Yellow wire: To enable the engine hours coun- ter and fuel counter; and to start the fishfinder automatically when the ignition is turned on, connect the yellow wire to the ignition system through a 2 Amp fuse.

Note: The fishfinder cannot be turned off while the ignition is on.

Secondary alarm wiring option

Green Wire: Use this to connect a secondary alarm indicator such as a flashing light or exter- nal beeper with a built-in drive circuit. See the Auto power wiring diagram.

If the external beeper or light requires more than 200 mA total, fit a relay. Consult your Navman dealer for more advice.

Fuel kit wiring

See the Fuel Kit Installation Guide for information about the fuel transducer cable.

Wire the power cable for Auto power (as de- scribed in this section) to make sure the fuel counter starts as soon as the engine starts.

For twin engine installation a T-connector needs to be installed on the fuel transducer cable.

Comms wiring

NMEA wiring option:

NMEA out: White wire - Use this, if desired, to connect the Fishfinder to other NMEA instru- ments such as Navman’s REPEAT 3100. (See section 6-6 Systems of several instruments.)

NMEA-1 in: Blue wire – Use this, if desired, to connect a NMEA instrument to the Fishfinder such as an external GPS source. Note however, to use NMEA-1 in, NavBus must be disabled in the Comms menu – see section 3-7 Setup > Comms.

NavBus wiring option:

NavBus (-): Blue wire: and;

NavBus (+): Orange wire: Use this, if desired, to connect the fishfinder to other Navman instru- ments such as Navman’s REPEAT 3100. (See section 6-6 Systems of several instruments.)

NMEA in: NMEA-2 in (White connector)

NavBus: Blue wire - NavBus(-) and Orange wire NavBus(+)

In all cases, both NMEA and NavBus reference
