Ok so I just bought a helix 12 g2n di for the bow of the boat. I have tried 5 different transducers, different mounts, traced power wire, grounded the trolling motor, farit rings everything!!! I am still getting interference on my graph, I'm beginning to think my trolling motor is bad and needs a new one to clear this up! The marine dealership also has been trying to get a solution to fix this! For 2 days they have tried everything and called humminbird with no luck! I am getting really upset that no one knows how to fix this issue with the trolling motor and the helix 12 interference! I'm thinking of returning all of this humminbird stuff and going with lowrance graphs! Please help me fix this if anyone on here has knowledge of fixing this I would greatly appreciate it! Thank you

That's not good! How bout you lowrance guys, you have problems with interference as bad as humminbird?! I'm thinking of switching to lowrance if I do not get it resolved! The cockpit unit runs flawless I have a helix 12 g2n mega si di gps with no issues at all with rfi!

You tried the trolling motor specific transducers? That's what I was going to try next.

Did you move it away from the trolling motor? Moving mine 6" or so got rid of the interference. I've had about 5 HBs on 2 different boats and only one ever gave me a problem. Others had worked next to the trolling motor. This on didn't want to

What TM brand? If it's a Minn Kota, check under the cover for a fuse that is blown. It can cause you issues with electronics yet your Trolling motor still work

what have you tried? What battery are you running the Helix on? I have interference on my bow Bird.. its an 859Ci and I'm running it off of the first battery in my trolling motor 24v string.. if that makes sense. I haven't taken the time to try and fix it. Its a stab in the dark to try and filter the power since I don't know what freq the control is operating at for the trolling motor. The trolling motor is generating the noise that is getting into the Helix either via radiation from the motor itself into the transducer or its corrupting the power to the Helix. My TM is a Motor Guide GW80 you didn't say what you have. The "farit" rings.. actually ferrite cores that are used to create an induction type filter.. but again.. they are frequency dependent.. meaning that a different mix of ferrite works on different frequencies so.. unless you know what freq the interference is.. you don't know which core to use. Finding some body with some RF knowledge would be a good place to start on getting that interference fixed. I know I haven't helped in fixing the problem, but I hope that I may have given you some background on what it is and how to approach fixing it. Good Luck

I run all of my graphs to the cranking battery, and both units have a independent lead running to the battery! I have tried all off the transducers from the tm ones to the transom ones! I now think there is a ground issue, I have to check if I have a ground wire running to the post of the cranking battery to the tm battery. This might solve the issue. Also I have read the mk charging system might be the the culprit! I think connecting the negative cranking battery to the tm battery with 18g wire will solve it I hope!!

Have you tried the Bird specific forums on BBC? They have a lot of technical information over there.
