Raymarine fluxgate compass has 4 wires + bare, not 5 insulated... normal?

[basssears]

So reading the manual for my Raymarine ST4000+ wheel pilot I expected there to be five wires in the bundle that comes off the fluxgate compass (blue, red, green, yellow, screen)... the previous owner was only using four colored wires (red, blue, green, yellow) and I'm told the wheel pilot was working before we bought the boat (trying to recreate that "working" now).

Seeing that there were only four wires being used and five plugs on the back of the control head I figured one wire had snapped off or something (was a pretty hinky install) so cut back the whole wire bundle and found four colored wires (red, blue, green, yellow) and one bare, uninsulated wire.

Is the uninsulated wire the "screen" wire that I have been missing? Am I supposed to put a connector on this bare wire and plug it into the "screen" plug on the back of the control head?

If not, am I doing OK running the system with just the four colored wires (like the previous owner did)? The whole AP starts up and looks normal to me, turns the wheel and everything, but I haven't been able to get out and test it yet, and I also want to know I'm not doing anything bad by running on only four wires from the fluxgate to the control head, not five.

Thanks in advance,

Yes you need a small female spade type connector for the bare wire, it is the screen.

Thanks... I have the spades from redoing the other wires so all good there, just didn't know what "screen" meant as a color. Odd that it appears to work without that wire connected.

iirc, screen is marked with a GREY position indicator on the instrument. 1/8" female spade needed.

Screen is just another word for the shield, or bare wire.
