Fish 4430/4431 Installation and Operation Manual
Warning
1 Amp fuses must be positioned where shown
in the wiring diagrams.
If possible, route the transducer cables away
from other wiring on the boat. Electrical noise
from engine wiring, bilge pumps and other
electrical equipment can affect the unit.
The shortest and most direct connection to the
boat’s battery helps to minimise voltage drop.
Ensure that any cable connections do not lay
in the bilge.
Two wiring options are described in this
section:
·
Basic Wiring.
This does not start the
fishfinder automatically when the boat
ignition is switched on and it disables the
engine hours counter.
·
Auto Power Wiring.
This must be used for
engine hours and fuel computer options.
Important
The FISH 4430/4431
must
be run off a 12
volt battery and must
not
be run off a circuit
without a battery.

Red wire
: Connect this to the 12 V positive
battery terminal after the main switch. Fit a 1
Amp fuse as shown.
Yellow wire
: To enable the engine hours
counter and start the fishfinder automatically
when the ignition is turned on, connect the
yellow wire to the ignition system, through a 1
Amp fuse.
Note:
That the fishfinder cannot be turned off
while the ignition is on.
Flashing Light and/or External beeper
(F4431 ONLY)
Use the green wire, if desired, to connect a
secondary alarm indicator such as a flashing
light or a 12 V external beeper with a built in
drive circuit. Refer to the wiring diagram. If the
external beeper or light requires more than
250 mA DC total, fit a 12 V relay. Consult your
NAVMAN dealer for more advice.
NMEA Instruments (F4431 ONLY)
Use the white wire, if desired, to connect the
fishfinder to other NMEA instruments such as
NAVMAN’s depth repeater. (See section 5-5 for
more information).
