(1) Tag and disconnect wires attached to time delay relay (1).
(2) Remove screw (2) and time delay relay (1).
b. Test.
(1) Using a multimeter set on lowest OHMS scale, check for discontinuity
across terminals 1(+)and 2 (-). Continuity should not be indicated.
(2) Using a multimeter at on lowest OHMS scale check for continuity and resistance
across terminals 3 and 4. Continuity should be indicated and indicated resistance should be
432K OHMS 5%.
(3) Set multimeter on appropriate voltage scale and check for 32 volts ac across terminals
3 and 4.
(4) Replace time delay relay if it fails any of the above test.
