Disconnect wiring connector. Using a hand-held vacuum pump, apply vacuum to vacuum switch. With vacuum applied to vacuum switch, continuity should be present between vacuum switch terminals. Vacuum should not drop suddenly. Replace vacuum switch if vacuum drops suddenly or if continuity is not present.
