- Test for infinite resistance between the signal circuit terminal 4 and voltage circuit terminal 3 with the switch in the open position.
- If not the specified value, replace the switch.
- Test for less than 6,800 ohms of resistance between the signal circuit and the voltage circuit with the switch in the closed position.
- If greater than the specified range, replace the switch.
