VSI - Replacement of Joystick

  1. Disassemble the VSI and identify the Joystick type, as described in [ Disassembly and identification of Joystick type ]
     
  2. Remove the Joystick as described in [ Replacement of Joystick Gaiter ]
     
  3. Fit the replacement Joystick, ensuring the notch on the Joystick is correctly positioned.
     
  4. Calibrate the Joystick with the following steps.
    1. With the Joystick Cable disconnected, switch on the VSI. This will enter a Calibration Mode, which will be indicated by the left-hand speed LED flashing as below.

       
    2. Connect the Joystick Cable and carefully hold the two halves of the VSI together as if re-assembling.
       
    3. Press the Horn Button. The left-hand two speed LEDs will now flash as below.

       
    4. Deflect and hold the Joystick in the full-forwards position and then depress the Horn Button until there is a bleep, then release. The left-hand three speed LEDs will now flash as below.

       
    5. Deflect and hold the Joystick in the full-left position and then depress the Horn Button until there is a bleep, then release. The left-hand four speed LEDs will now flash as below.

       
    6. Deflect and hold the Joystick in the full-right position and then depress the Horn Button until there is a bleep, then release. All five speed LEDs will now flash as below.

       
    7. Deflect and hold the Joystick in the full-reverse position and then depress the Horn Button until there is a bleep, then release. All the speed LEDs will extinguish, but all ten battery gauge LEDs will flash as below to indicate the calibration sequence is complete.

       
  5. Switch off the VSI.
