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?
