6 Installation and Maintenance

Correct installation is critical to the performance of the FISH 4432/4433. There are two components to install, the display unit and

the transducer. It is vital to read the entire installation section of this manual before attempting to install the components.

Wiring Options

The power/data cable contains 5 wires:

Warning

1 Amp fuses must be positioned where shown in the wiring diagrams.

Six 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 the engine hours and fuel computer options.

Secondary Alarm wiring

NMEA wiring

Single engine fuel wiring

Twin engine fuel wiring

Note: If a wire colour is not specifically mentioned, it is not used in that wiring option.

Section 6-5 Systems of several instruments, describes NMEA and NavBus.

Basic wiring

This requires the FISH 4432 and FISH 4433 to be powered on manually with the key.

Black wire: Connect this to the negative battery terminal.

Red wire: Connect this to the positive battery terminal after the main switch. Fit a 1 Amp fuse as shown.

Yellow wire: Connect this to the black wire. This disables the engine hours counter.

Power on the fishfinder manually whenever the main switch is on.
