  • When power is applied to the charging connector it activates a relay which disconnects the power to the main circuits.

  • The main powerswitch is under the large yellow lever and simply applies power from the battery to the control board in the console.

  • A multipole switch is used to reverse the direction of the motor

  • An LED in the console flashes with the sound

  • The sound is provided by a loudspeaker in the base
