Just put a 597 combo on my bow. I have a 24v minkota with built in transducer. I have the unit wired to my starting battery, but as soon as I run the trolling motor it goes fuzzy and looses signal. Any suggestions?
you need to run a seperate 2 battery system to get 24 volts and it should resolve your interference issues
I have two battery systems. The two batteries for the trolling motor and a 12v off the starting battery to the depth finder.
I have had good results by running a second ground wire from the depth finder to the anode plate on the motor. Another option is to run this wire to the skeg on the Minn Kota. The theory I believe is that you use the water as a ground for the noise.
Call Humminbird customer service and get them to send you a trolling motor interference kit with chokes. Install and problem should be solved as long as the rest of the wiring is to spec’s. Free and easy.
Thank you for everyone’s input.
