• Continuity Checks: Using an ohmmeter, there should be no continuity between terminals 2 and 1, 3 and 1, or 2 and 3. If there is continuity, replace the switch.
• Operational Checks: Connect a battery between terminals 3 and 1 as shown. No continuity should be seen between terminals 1 and 2. But, when the switch is pushed "on," there should be continuity. If operation is not as specified, replace the safety cancel switch.
