This is trolling motor on and off

Got an I pilot PD V2 and a 787c2 mounted up front. Turn on TM and bird goes crazy. I've asked this question before and got the answer to hook up to separate battery. Finally ran 3rd battery with power wires on the other side of the boat and it's still doing the same thing.
No transducer hooked up, wires ran on other side of the boat from trolling motor power wires, separate batteries, and I'm still getting the same thing. Any suggestions now?

I would highly recommend to put your boat in the water before you come to the conclusion. Water adds a grounding element that is hard to duplicate out of water. Not uncommon at all to have rfi out of water but then clears up when on the water and vice versa.

pull the top off the trolling motor head and check the fuse in there. its probably blown. if it doesnt have the fuse in the head. run a ground wire from the skeg to the negative post on the battery. be sure to put a fuse inline. it looks like you got the transducer cable wire tied to the trolling motor wires. separate them and see if that helps. do you have a onboard charger? some onboard chargers use a common ground try unhooking the ground wire off the trolling motor battery.

Transducer is not plugged in and no on the big knot of power wires. Only about 12" of extra power wire ran.

It has not been in the water since I added the 3rd battery but it did the same thing when it was hooked up to the same battery as the trolling motor. Will try to get it in the water this week

I had the very same issue as you with a 597 on the bow. Transducer was mounted on motor. I disconnected ducer, dropped motor so I could turn it on. While running motor I move ducer around and away from motor. Made no change. My power wire was like yours which is original. I called Humminbird and told them my problem and asked about getting the updated power wire with ferrit ring installed. They sent me a new power wire with the ferrit ring installed. Installed that new power wire and that solved my problem. Might give that a try. Sure can't hurt anything. By the way if you decide to run motor out of water just run it on low for short period of time then shut off for a bit so it dosnt get hot. Uses water to keep motor cool.
