having trouble with my new depth finder
i have 24volt motorguide (70some thrust) trolling motor, and connected my depthfinder to trolling motor batteries.
two 12 volt batteries connected in series, only tapped into one side of battery of course....depthfinder 12v syst.
my depthfinder works great until i turn on the trolling motor, then the screen goes black suddenly.....
only my depth feature is on....whole screen moves but in black.....
any suggestions??
is it frequency interference?? cause of wireless trolling motor or do i need to get separate battery for depthfinder??
thanks guys!
