i had an older lowrance hooked up to the us2 cable and had no problems, since i have installed the 898 i get horrible interference when the trolling motor is activated, i have put chokes on the power cables to the trollling motor, the power cable to the 898 and on the transducer cable with no success, do i need to buy more chokes and put some on my food pedal cord also, thats about the only thing i have left to choke or i am going crazy, what other options do i have?
Have you checked your fuse under the head in the TM?
everything is getting power, what do i need to check the fuse for?
Because the noise reduction circuit in the US2 is protected by a fuse, and when it blows they are prone to interference.Quote:

i willl check that first then proceed.Quote:

Before you try too much, it can help to pull the unit's power cord out and hook it to a battery outside the boat and see if you still get interference. Do you still get interference with the motor on 100% ? If so, you could be dealing with brush issues in the motor.
I've got a 788 DI that I eventually moved from the bow to the console because I could never solve my interference and guess what, it still happens back there if you check it while running the ipilot. Sure does such to pay so much for items that won't work correctly. Put a 570 DI up front btw and never have had a problem.

RF interference is definitely an elusive monster to track down sometimes...:donoQuote:

Run the fishfinder and watch the interference while clicking to different capacitor values on the box. When you find the one that kills the interference note the value, Buy one of that value and strap it in.

well i have run a ground from the negative on the bird the to transducer clamp and have wrapped it really well around the transducer cord and it has helped some but still got a lot of interference, getting ready to call humming bird then the local electrical repair shop.
also as a side note i have a 898 at the console that i get zero interference with.
going full throtttle takes out almost all of it.Quote:

Got a buddy who had to do the same thing and he's the one who told me about it. I have same TM also and exact same problem so give the seperate battery a shot.
This is a normal sequence in RF and the "Maximizer" feature of the Minn Kota trolling motors...Quote:

We have to remember that DFs don't create RF ... They are just sensitive enough to pick RF up that created somewhere else in your boat...

i had the batteries charging this evening and it was picking up the charger though it was very slight, i connected the power to a seperate battery and that did nothing, talked to a nice lady at humminbird and she is sending me a few things to try but she did say that in a few cases it was not eliminated, i double checked the 3 amp fuse in the head of the terrova and replaced it for the heck of it and that wasn't it either, and i can't find anyone that has a capacitor decade box as of yet. ya'll keep your fingers crossed.
well i figured i would give an update, i have yet to find anyone that has a decade capacitor box, but i did recieve three chokes from hummingbird, they are a bit larger and round and one piece compared to the square two piece ones i got from radio shack, i put one on the power one on the transducer and one on the gps like the nice girl at humminbird said to, i then put the other chokes i had on right where the cord comes out of the transducer, one where the wire comes out of the foot pedal and one where the foot pedal cord comes out of the motor and ofcourse i already had two on the main power cord for the trolling motor, this cleared it up about 95%, i believe i can live and fish with it effectively like it is now, not perfect but dang close. i do wonder though if i got another choke on the power cord and the transducer if it may take it all out?
Gobbler... has HB recomended this ...??
TMC 1 :: Humminbird

they are supposed to be sending me one but they were out of stock and it would be a couple weeks, i will probably add it to the collection and see if it takes out the last little bit of interference. the girl i talked to said that thing was about a 50/50 shot.
I was having the same problem with the 798 I had on the bow. I now have a 788ci HD DI there. I installed the choke that humminbird provided & also bought a cheap, small inner tube. I cut the tube long enough to wrap around the TM housing then split it down the middle. I then clamped the transducer mount around that. Cleaned mine up. I also have my electronics hooked to their own battery.Quote:
