3. 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.
- Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).
