Trolling motor interference on a FL-18

[chucker]

I just installed an vexilar FL-18 on the bow and an older vex puck transducer onto my bow mounted AP65. I am picking up interference when the trolling motor is running? I have been told inserting a piece of rubber between the trolling motor and the transducer should solve this? Anybody else had this experience and how did you solve it.

Thanks

I'm betting you wired the Vex to your deep cycle batteries that power your trolling motor. That will create lots of interference. Wire it to the starting battery.

Vex is wired into the fuse panel that is powered by the starting battery.

Give the rubber a shot. Have you tried the IR on the Vex?
Besides electrical interference I wonder if vibration from a prop might be the problem.

Yeah my marcum does the same thing at times, I've found it best to keep the gain low, and trying different interferance settings, I'm actually thinking of mounting the transducer else where. I doubt rubber will have much effect, still worth a try.

BTW my battery is totally seperate, and it makes no difference.

I talked to the guy @ Action Electronics in Ramsey. He told me to run a fusable link from my #1 deep cycle battery negative post(ground) to the negative wire of the vexilar power cord. I tried that last night and the Vexilar would not power up (positive lead running from the starting battery and negative running to the negative on the #1 deep. Thinking about it a bit...I think I'm going to try connecting the fuseable link conectected to #1 deep cycle to the negative vexilar lead and the negative lead going to the ground on the main fuse panel. This should ground all the batteries together (starting battery and deep cycles) this is probably what the guy from action told me to do in the fist place. I hope this makes some sense, I give you a report tomorrow morning.
