Installing new NMEA network on ranger 481v

Recommended Posts

Hello, 

I have just purchased the boat in a box from tackle warehouse which includes two HDS 7 lowrance fish finders a one point antenna and a nmea starter kit. I already have two gen 1 HDS units that were installed on the boat so I have power to the fish finders my problem is adding switched power to the nmea system I'm not sure the correct way to go about this. I do not have any available switches to add this to a switched power source. Can I power the fish finder and nmea network off of the same switch or what is the correct way to add more accessory switches. I would like to get a better grasp on this before I dive into the wiring for the boat. 

Thanks Cody

You can wire yours using the yellow wire.

For your N2K power node, run the blk wire to ground, red wire to the bat/fuse box, and connect the yellow wire to the yellow wire of one of the HDS units.

This way when you turn on THAT HDS unit, it will wake-up and turn on the N2K.

If you install a new switch just for N2K there are a couple of ways to wire it. blk to ground, red and yellow to the powered switch (easiest). The other way would be to use a non-powered switch for the yellow wire only.
