Fusion® Stereo not Turning On

A Fusion® stereo has a ground wire, a power wire, and some have an ignition wire. Ground is always black, and if no ignition wire is present the power wire will be red. If an ignition wire is present, the power wire will be yellow and the ignition wire will be red.

Power and ignition wires must be connected to a 12v power source, and the ground wire must be connected to the ground of that power source.

The power wire is the high current supply wire and should be connected using 14-gauge wire, or 12 gauge if extending more than 1 meter.

The ignition wire must be connected to a 1 amp fuse and can be extended using 22-gauge wire. It is a switched input and will turn the stereo on when it receives power.

The Power and Ignition wires may be connected to the same power source so long as there is a switch on that source to allow the stereo to turn off.

Once all connections have been verified

• Check that there are at least 12v going to the Power and Ignition wires

• Disconnect and reconnect the wiring harness from the stereo

• Check that the harness is seated firmly within the port

• Check the vessel batteries for sufficient charge and turn on the main switch and switch to the stereo

• If a remote, MFD, or chartplotter is connected, try to power the stereo on from that device

• Unplug the power harness from the back of the stereo and inspect the rubber gasket around the plug for any damage and the pins in the plug and stereo for any damage or corrosion

• When plugging the power harness into the stereo make sure it plugs in completely and securely with a small click sound

• Check the fuse at the panel the stereo is connected to as well as the fuse in the back of the stereo

• Check wires for any damage or corrosion

• Remove all connections including power from the stereo for 15 minutes, then reconnect only the power wiring harness
