Garmin 501c issues

[Wiggy]

I have a Garmin Echo 501c that I have installed on my Minn Kota Powerdrive V2 trolling motor but seem to be having issues with it. I'm not really getting a clear picture of anything, especially while I have the trolling motor running. When I hit the accelerator on the trolling motor the graph will just turn into a bunch of what looks like lines below the bottom and nothing will appear on top. When it's off I will occasionally get something to happen but even over areas where I know there is brush I get very distorted signals and definitely don't see the brush like I feel I should.

I have adjusted the gain and noise reduction repeatedly and never found anything that would work.

One thing that could be affecting this is my father was helping me install it and went to drop the motor to test it out, only to pinch the transducer cable when he did and skinned some of the casing off. We wrapped it in electrical tape and didn't think it would be an issue but could it be?

Pic is of the little lines that appear and nothing above the bottom while trolling motor is on. I have video also, might try uploading it to YouTube.

This would be a good test for Garmin Customer service ..... Give them a call to see if they can offer suggestions.... Please let us know how it goes.

Might be an RF issue. There is a sticky regarding some of these issues and you may find some tips there

Thx vic, heard from tech support a little while ago, no answers yet, just wanted to verify I was using the transducer that came with the unit and not the one in the trolling motor and that it was a new installation. I'll keep everyone posted.
