My tm is on its own battery min Kota Trevor. (Sp). Doesn't go through any switch fused panel all direct connect to batt. Bow mount tm with ft control cable lying on floor back to drivers seat where I fish viewing my graph.
my humming bird graph somehow is picking up interference at speed #2 an3 on trolling motor speed control only. 4 through 10 no issue
i can turn the sensitivity off all the way down an intereference goes away but I lose any bottome detail
(normal bottom dept between 18 / 30 ft)
The interference appears on the graph screen in solid colors,
hope someone one can give me a clue
