My Terrova is acting like it’s stuck on autopilot. When I deploy the motor, and if the speed wheel is on anything other than zero, the prop begins to spin. The autopilot light is off. The prop on/off button on my foot pedal are useless. The only way I can use my motor is to spin the speed wheel to move and to stop I have to spin it back to zero. If the speed wheel is on anything other than zero the prop automatically begins to turn. If I disconnect the foot pedal the prop stops. Any suggestions as to what my issue is?
