Is your 859 wired straight to the starting battery or somewhere up in the bow area with the trolling motor?

Wire direct to the starting battery and contact Humminbird and they will send you a ferrite ring

1st option wire to starting battery
2nd option only after 1st option is ferrite ring.

Also I have seen where the Humminbird unit was moved away (to the right) from the trolling motor 4" and the unit cleared up.

I have not ever put a ferrite ring on the adpter cable for the US2 transducer. Not sure why you are getting interference. Seems you have everything connected correctly.

Try going into menu and switching 2D to the US2 transducer if there is an option on that unit. I can't recall...

Interference can be caused by many things such as cable routing, worn brushes and water intrusion from the trolling motor, on board battery chargers. The ferrites are just one remedy that can work for some and not others. Its a process of elimination. One of the most common solutions is to separate the trolling motor power cables away from the transducer cable if possible

They are not together.. trolling motor wires are on the right side from center console and transducer wire ( 30 ft ) is on the left .. now , they are close right in the center where they com into the console.. I cant help that.. when I say interference, better description is it fades .. like I lose some of the signal.. not like lines straight up and down interference, if that makes any sense .. and when I am on the anchor feature..

I have the Ternona .. It's about 3.5 yrs old .. Do I need to check to see if mine has the fuse ?

Humminbird makes a in line choke you run the TM power through as close to and before the TM. I have used it several times on several different boats to eliminate the problem you describe. They were also wired straight to the battery and the choke eliminated the interference.
