    Didn't help. Every power wire possible has a ferrite ring scotch tape would have been
    About as usefull.

    you ran a ground straight to the transducer mount? If so its a bad transducer or power wire issue.
    you need a dedicated power wire to battery.

    I was using that same wiring and had an issue until I ran new wire direct to the battery. That accessory wiring run through the boat's wiring harness and can introduce interference.

    I will go with that next. running wire and trying to get every thing in place is for the young guys....
    cant be worse than the trolling motor mount screws last week.
    I would have thought that thick a wire was run direct to battery and not the harness. don't remember it being tied to power switch.
    thanks for the info.

    for older graphs I had them direct to trolling motor batteries for awhile.
    after getting a no start at 3 in the morning 10 miles from truck and no jump starter you know who your friends are.....

    On my 92 it is 10 ga strait to the battery cut off the plug and used it to power my helix 10 buy its self
    the 360 mega runs off the on of acc switch on the bow pannel ground drain is on the same wire as the 360 ground .
    seprate from the helix no interference on 2d on the ultrex or the 360 works great.

    Well something worked. The aluminum wrap around the rubber under the transducer?
    Ground wire from foot to ground in boat? Ground from foot pedal to tray ? 10 pack
    Of ferrite chokes on every wire possible up front ? Who knows just be glad it Works correctly
    Just been putting up with it for years.
