Got an I Pilot PD V2 and ran my transducer cable through the coiled power supply wires down to the motor. I'm getting RF interference when the motor is running but when I turn it off it goes back to normal. What can I do to fix it?

Separate from the power wires or use a TM version transducer which has shielded wiring might work.
I'm using a tm transducer but I will take it out of the coil power cord and see if that helps

check to see if there is a fuse in the head of the trolling motor. if there is one its probably blown.
Try using a ferrite ring. Wrap around your transducer cable right before it goes into the back of the unit.
Have to try the ferrite ring because I've taken the transducer completely off of the trolling motor, taken the cord out of the coiled power cord and it's still doing it. The unit itself is about 12"away from the base of the TM. Unit works fine until I turn the TM on. It doesn't seem to increase when I turn the TM up on a higher setting either. Does radio shack have ferrite rings? And are there different kinds and sizes?

Can also happen if sharing the same power
Two totally different power supply points. Wires for TM run on one side of boat and wires for depth finder run on other side of boat

Another few tricks are to run a small ground wire from the ground on your battery to the transducer clamp and another is take a piece of inner tube and put it underneath your ducer and clamps to insulate your metal from touching the tm itself
I was going to try aluminum foil between the transducer and motor housing but it still does it without even being connected to the TM. The closest thing to the TM is the unit itself and it's about 12" away. Didn't do this at all with the other TM. An EDGE

The noise is generated by the variable speed PWM, so 5 speed motors don't do it. First troubleshooting step should be to operate the motor on 100%. If the noise is still present, your problem isn't RF.Quote:

Catfan --- on the rite track, it is being back fed through the power supplying the power. An on board charger that is connected all the time could be where it feeds through
I'm thinking you are hitting the nail on the head. Turned on TM and it only does it on half's. 1,2,3,4 and so on it doesn't do it. 1 1/2, 2 1/2, 3 1/2 all the way up to 8 it does it. At 9, 9 1/2, and 10 it doesn't do it.Quote:

Is there any solution short on me adding another battery? I'll have to cut a hole in the front deck and that's going to be a pain and expensive and I don't have room in the back off the boat to add a 3rd battery.

I’ve heard of pulling the fuses on the charger to stop back feed
The shared battery is the problem. You just can't do that without causing interference.Quote:

Probably not as sensitive at the frequency you are using or better at filtering the noise.Quote:

Using two dedicated TM batteries is the best option if you can manage it.
I had that problem with my power drive when I went to a HDS , , I used the rings first didn't stop it, ran a ground wire from my - post to the housing on the motor, that fixed it. been working 2 years now.
thats what i did on my pd. it fixed the noise issue i had. i added a fuse like the factory ones have.Quote:
