Lowrance Help

[KAYAKLIPJERKER]

These are two screenshots from the Lowrance units I have on my small boat. The Elite 5 Chirp is on the front and the HDS 7 Gen 2 is on the back. I recently changed the trolling motor to a Minn Kota Powerdrive foot operated system and after changing it out the interference started. Also it only occurs when you press the foot control to move the boay. Anyone have any ideas on how to stop this interference?


The pic of the HDS 7 is on the downscan structure screen and I'm getting very little if anything on the screen. Any Ideas?



Thank you!!

PWM issues. Is your TM power wires near your sonar wires? Is your sonar powered by your TM battery?

Well you need to get the sonar cable off the cables to the TM and keep it from touching the steering motor. If this is a 12V power drive, make sure they are not on the same battery. Other than that, there should be no source of interference so if that is not the cause, I am stumped!

Thanks for the answers guys.

This is on my small boat which is a Gheenoe LT25 with a single battery 12v system. I may have to look at adding another battery for the two depth finder units.
