Thread: One big headache

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.

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

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

That makes sense. My Helix has that power cord and it has no issues.

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.
