Thread: HB depth reading issue

Received a 2887313 ferrite bead from HB with instructions..."remove the two motor side plates and control board cover to expose the main control board. Locate and disconnect the red motor positive and black motor negative wires (red and black coil wires).....I'm understanding this to mean to take off the "minn kota" covers on the both sides of the motor and get to the coil wires down there where they leave the motor instead of up in the trolling motor head. Right?

Got it done. Will test after lunch.

Tested ferrite bead...no change in interference.

Turn the console unit back on Boatbottom and try turning on and up the Noise Filter menu in the 898 unit and see if that works for you.

Will do. Just got this boat and have also discovered my si is not working. I get a very light screen and no detail but when I turn off the trolling motor the screen detail is great. The three amp fuse in the I pilot was blown so I changed it yesterday and tested. Still no si. Am going to check the fuse again today. I have a three bank charger Should I unhook it from the crank battery? Thanks

I would try if the fuse in the trolling motor is blown again as something is causing it to blow. If you can't find anything, try calling the Humminbird Customer Service folks to help get it sorted out. Trolling motor interference is sometimes difficult to overcome, so be prepared to try multiple things to get this fixed.

if you're trying to get SI with the US2 built into the trolling motor, it won't work. US2 is only 2d sonar.

Using my own transducer. Trobleshooting said a blown fuse in the us2 line can still cause interference even though you're not using it. Thanks for trying

That fuse is on the ground line to the foot of the trolling motor. If it blows there may not be a good ground source for the motor and it may start radiating RF energy (aka: trolling motor interference). Something caused the fuse to blow and that is what you need to eliminate.

Ok. SI still getting interference. I have checked the fuse I put in the trolling motor and it's still good, increased the noise filter to high, disconnected the cranking battery from the 3 bank charger. Guess the next step is to call HB.
