wiring HB859ci HD DI

[Hue]

Ok all you old pros...what is the best wiring solution for my new 859HD DI?
My current small graph at bow was connected to trolling motor wires when I bought the boat. I have cranking battery and 2 trolling batteries.

if it's the only thing going on the wires, run 14 or 16ga wire from starting battery to the unit and you should be good to go.

Thanks for the reply Wannabe.

Using twisted pair helps eliminate interference.

Bill, what do you mean twisted pair? I'm about to tackle this same project. Thanks

Take your 2 wires, make sure you have more than enough to reach from battery to hookup. Tie a over hand knot at on need leaving about 6-8 inches tag end. Hook it ove something to hold it then take your 2 wires and twist them together until you get to the other end. Don't have to be real tight. Put a piece of electrical tape close to the end to keep them together. Then make your wire run through the boat. Once you have that done and wires secured, put ends on to connect to battery. On finder end solder a blade type fuse holed into power wire then solder in red power wire from finder. Solder ground wires together. Make sure to use some heat shrink over connections. Once that is done connect to cranking battery. Twisting the wires in this manner stops a lot of external interference.

I use an cordless drill to twist them together. Be sure to start with plenty of wire because the more you twist the shorter the wire gets.

Thanks a bunch guys. I knew someone out there had a more tried and true method for me. As much as the units cost, I definitely want it to perform the way it is supposed to. I always worry that I am going to tear more stuff up than what I install.

thanks again

I would make sure to put the fuse holder on the battery end so that it protects the boat’s battery if the cable gets shorted somewhere.

Gotta partially disagree with you on that one Greg. Fuses protect people not equipment.
