I have a Helix 10 G2 mounted at the bow. As soon as I engage my trolling motor I start getting interference and it will give me readings if 200-300 feet deep and no picture, as soon as I let off the pedal it goes back to normal. Anyone else experienced this?

Do a web search for trolling motor RFI. There has been thousands of discussions about it for at least 50 years.

Then after you see your situation is not unique, contact Humminbird Customer Service for help with that issue.

Humminbird will probably send you something to help with interference for free

What TM are you running?

I have the exact same setup and they told me to make sure all the wires at the trolling motor are not near each other(especially if it is not shielded wire)

They (ultrex) have a 3A fuse in the head, change it to a 5A and your interference issue should disappear.... Little tip I got from Slade Dougharty (the graph guru)

I ran dedicated power wire to battery and 1/2 inch rubber on bottom of tm housing and mounted transducer on that. Helped quite a bit.

Do not tape-tie transducer cable to the trolling motor cable. Run it along side the trolling motor top bracket.

That makes no sense electronically.. the size of the fuse makes no difference as far as RF interfering with the DF. The accepted way to hook all of the pieces is the DF is powered by the crank battery and the ground of the trolling batteries and and the crank battery are connected together. Not all of the grounds in the series connected trolling batteries, just the one that represents zero volts to the TM. Also, the transducer cable should be kept as far away from the power cable of the TM as possible. I have braid shield over my power cable to the DF, tied into the ground of the power to the DF. I have eliminated just about all of the interference I was getting.. that was with a Motor Guide Great White 80lb and now with a Xi5. I'm not using the internal transducer on the Xi5. I think to get it all out, the transducer cable needs to wrapped around a toroid core but since those things are frequency dependent and I don't know what frequency is interfering.. I don't know which one to buy. Good luck with your efforts.. its not rocket science but its tricky just the same.

More than likely, what Slade meant was that the 3A fuse was blown. You will see interference if it's blown. Then he replaced it with a larger fuse to help keep it from happening again.

I have the exact same problem with my Humminbird HELIX 5. It worked perfect for about 4 months then it just started doing this. I had just replaced my on-board charger with a new one so I disconnected it and it still did it. I ran dedicated wires straight from cranking battery still does it, so if you find a fix let us know.

I've got pretty much the same problem with my Helix 7 DI GPS. Ran a dedicated wire straight to battery and helped a tiny bit. Still struggling with it. It's a POC, IMO, cause Humminbird was not much help at all.
