a. Inspection.
(1) Be sure power has been disconnected at the source then disconnect input power cable from switch box.
(2) Remove 10 screws (1) and carefully pull switch box cover (2) out as far as wire leads will allow.
(3) Check for damage, deterioration, or missing parts. Based on the inspection, determine if the switch box
assembly can be repaired or if it must be replaced.
b. Testing.
(1)
Using multimeter set to measure continuity, check each switch (3). Place both switches on the OFF position
and check continuity between matching color leads on top and bottom of each switch. Replace switch if
continuity was indicated.
(2)
Place both switches in the ON position and check continuity between matching color leads on top and bottom
of each switch. Replace swi tch of no continuity was indicated.
(3)
Using multimeter set to measure continuity, check between ends of wire leads at terminal connections.
Remove pressure switch and motor covers as necessary and use electrical schematic (Figure 1-3) for test
points. Replace any wire leads that do not indicate continuity
