Interference on my 360

I am getting interference on my 360 when the troller is running. Here's the set up:
360 transom mount
Heading sensor puck mounted just in front of it.
1198 at the console
1199 on the bow
112 Ilink Terrova
All link through the black box.
ALL power for 360, Depth finders and box is on their own battery.
Terrova is connected to 3 batts of it's own with its own charger.
Aux batt and cranking batt have their own charger.
I'm scratching my head and the interference is not letting me get it dialed in.

First pic is with the troller on, the other 2 are with me turning it on and off

That looks like the wrong pattern for 455kHz crosstalk ...

And it seems you already have the power circuits completely separated ...

If your electronics battery and TM batteries are in the same cargo hold - you could test with a small battery for the 360 on the deck completely away from any other battery source ...

Have you called HB ...??

I haven't Ricky, will do that from the water. No service at Sardis where I need to be but may force myself to go to Grenada for a little while tomorrow. The trolling batts are upfront and the cranking and aux batts are in the bilge.

The only connection cray and I count come up with is the Ilink being hooked to the black bkx

Another test would be to disconnect all Ethernet and connect the 360 directly to the console unit ...(preferably with the 360 Ethernet cable above the deck where it's unlikely to be close to any power wires) ...

If the interference is still present it would indicate the interference is getting in the 360 power cable instead of possibly the 360 Ethernet cable ...

As it stands now, we don't even know if the interference is encroaching into the 360 power circuit or the 360 Ethernet cabling ...

Could u try unhook in your chargers

No that's not 455khz cross talk. (I wouldn't use the Humminbird chokes,unless you can't find the source of noise)...your ethernet switch maybe getting noise through your battery charger?

Charger is in no way connect to the troller kosmo. Will hook it straight to one of the units and try it.

Saw your other comment kosmo. I can disconnect them before I go back out and see. May be able to duplicate this at home too.

I had to use the donut on my Terrova 80 lb and my standard unit. After that no more issues, but that is different then your 360 and terrova issues.. Thought you were getting the auto deploy unit? That will be my next T/M.

They recalled em bout the time I was going to get it and the rest I will share with you at camp

Hows it looking for catchings lots of fish next Wed,Thur,Friday and Sat? Don't care if most are short fish. Would love to be able to get Marilyn into a lot of crappie. Keepers or short fish does not matter.
Pete

Get plenty of minners, you will catch plenty of fish

Had interference on my network on a 1198, and a 998 with a 80lb terrova. Got a hand full of ferrite cores from Radio Shack before they closed locally and put them on the cables. It helped, but the interference was still there. Added a separate ground wire to the the skeg and it cured all the interference. Have since added the 360 and the ethernet switch with no problems.

RCC, can I get a picture of this?

did you remove the ferrite,filters?

I unhooked the Ilink and will see first thing in the morning

No change, no dependable service on Sardis so no calling humminbird either. Hooked it back up and will fool with it after the tourney this weekend.
