  3. Remove the two screws, and the engine start/stop switch.
  4. Check for continuity between the terminals in each switch position according to the table.
    NOTE:
    • Make sure the correct test lead (+ or -) is placed on the terminal.
    • When checking for continuity across the diode, use the diode setting on the digital volt/ohm meter to check the diode bias.
    • Be careful of this characteristic; a diode is one that conducts fully in one direction (forward) and not at all in the opposite direction (reverse).
