Connecting to Power Without Using an Ignition Switch

This method of connection is used most often on larger vessels and on vessels with multiple networked

stereos and other marine devices. For these installations, a faster startup time is typically less critical, and it is

more effective to use the breaker or a dedicated switch on the electrical panel to turn off the stereo and ensure

that no unexpected power drain occurs.

1 Consult this diagram to plan the wire connections.

Item Description

Yellow wire

Red wire

1 A fuse (not included)

Manual switch

(optional)

Black wire

15 A fuse (not included)

15 A circuit breaker

2 Route all wires to the stereo wiring harness, the circuit breaker or switch, and the power source as

necessary.

Do not connect the wiring harness to the stereo until after you have made all of the bare wire connections.

3 Install all of the necessary fuses on the red and yellow wires.

4 Connect the wiring harness to the stereo.

When the circuit breaker or manual switch is closed, the stereo is always on. You can use the power button on

the stereo or a connected chartplotter or remote control to place the stereo in a low-power standby mode if

needed.

NOTE: When you are not using the vessel, you should remove power to the stereo using the circuit breaker or

manual switch to avoid draining the battery.

Notes

You should connect this wire to the red wire before you connect both

wires to the manual switch or circuit breaker.

You should connect this wire to the yellow wire so that it does not act as a

physical standby switch.

You must install this fuse on the red wire before you connect the red wire

to the yellow wire.

This switch is needed only if a circuit breaker is not available or if it

provides a more convenient method of cutting power to the stereo.

Ground (-)

This fuse is required if you are not able to connect to power through a

15 A circuit breaker

If a circuit breaker is not available, you must connect a 15 A fuse

the yellow wire
