Default Raymarine C series installation expierence?

Just bought a new c series and have some installation questions.
1. what is a suppression ferrites and how do they work?
2. What is a scotchlock connector? is this just a easy way to splice?
3. The power cable has 3 wires. Power ground and then one small silver uninsulated wire? What is this small silver wire used for?

The Scotclock connection it a moisture resistant connection. The silver connection should run to ground... check your book.

The ferrites you asked about are to suppress EMI noise! To get into a technical explanation of how they work is beyond the scope of this forum. Technically they form a magnetic field that is tuned to suppress noise in the power line, they act as a resistor and coil in series. Just let it be said that if you don't use them as described in the owners manual your unit will not work correctly and will be prone to pragmatic outages.

As said the Scotclock connector is a moisture resistant connector, remember her when salt water vapor is allowed to come in contact with wire you end up with corrosion, over time the corrosion will become resistive and can cause you unit not to work properly.

The silver wire is a shield and on some units is used for the negative side of the communications buss. Check your owners manual for the proper connection.

Can't tell if you are an experienced installer or this is your first go at it. Be aware that a botched install will void your warranty with Raymarine. Better to hand this over to professionals if you feel you are really green when it comes to stuff like this. If you are familair with this and have done other electroincs work , then have at it....

the silver wire would go to a grounding plate if you boat has one. Most small fishing boats (less than 30') or 'trailerable' boats or probably 95% of the boats the users of this forum have don't have them. So, connect it to the ground or install a grounding plate (google it, or search WM BM on-line catalogs) and strap that would be connected to the water in some location on your boat.

Check out the Raymarine web site and read the manual.

Suppression ferrites are usually on power leads and they act to suppress noise. Sometimes they are used to suppress incoming noise, sometimes outgoing. In point of fact, I moved mine up and down the power lead to try to suppress the noise created by the C-80 that was picked up by my nearby VHF. Only partially successful. Gonna try more ferrites.

You will find a small bag that contains little round plastic thick disc "thingies" about 3/8" round with holes in the side. They're precisely what you intuited. Quick way to connect wires. Stick them in the holes, squeeze the disc with pliers, instant connection. Your phone company uses them by the carload.
