Ok, I have a new to me (thanks Oyey) 74# Power Drive Minn Kota trolling motor. I believe it's from 2004ish.
Anyway, it has autopilot and the universal sonar with this unit. The first time I used it, I noticed it caused problems with my existing Humminbird sonar. I have my HB transducer mounted on the lower part of my hull, in the back. The problem I have is when the t-motor is actually running, it causes the graph on my HB to pretty much just disappear.
My assumption was, since the cable for the universal sonar was not connected to anything, it was causing the interference in my HB screen display. Seeing as my head unit was up front near me and the bow mount motor.
Well, I also got a new to me (thanks, Discloco) Lowrance X125 (the adapter I have on the t-motor is for a Lowrance). So, with some help from a couple of friends, we rerouted the wiring for the HB, moving everything to the rear of the boat. I then installed the X125 where the HB used to be, and plugged into the universal sonar in the t-motor. On dry land, I wasn't getting anything really for readings, but everything powered up and worked.
Once on the water, and in use, total nightmare! Neither unit worked worth a damn when the bow mount motor was on. Clearly, the bow mount is the motor that we primarily use all day when we're out on the water, so in essence, I was fishing blind, or at the least, vision impaired.
By the end of the day, the Lowrance wouldn't even graph at all, just black streaks. I changed all the settings, even reset to default settings.
Not sure what's going on, but I'm getting very frustrated. Anyone on here have issues with their universal sonars? I have to think it is related to the universal sonar, I had no problems before installing this trolling motor.
Any insight would be greatly appreciated.
Thanks in advance,
