TM54930-230-13c. K-1 Relay Test Procedures.(1) Step 1.(a) Place ON-OFF switch in OFF position.(b) Disconnect Power Cable (J2).(c) Unscrew and remove Junction Box Cover with O-ring.(2) Step 2. (See figure 4-25.)NOTEFailure of Motor Thermostatic Switch can prevent relay operation.(a) The “X” circuit of the relay is grounded through the thermostatic switch in the motor, Tocheck continuity, put probe on “X2” terminal of relay, and other probe on negative (-) terminal of the J2Connector. (See wiring diagram in figure 4-24 for wire connections.)CAUTIONThe followlng teats require the power cable, J2, be connected as in normal(b)(c)ground.(d)reading.(e)pumping procedure. Exercise care in use of multi meter test probes.Connect Power Cable (J2).Hold negative (-) probe of multimeter on inner threaded portion ofTouching positive (+) probe of multimeter to “A1”. Terminal of relayAll other relay terminals should have “O” readings.(3) Step 3.(a) Place ON-OFF Switch in ON position.(b) Ground negative (-) probe of multimeter.(c) Touching positive (+) probe of multimeter to “X-1” terminal of relayreading.(d) Touching positive (+) probe of muitimeter to “A-1” terminal of relayreading.(e) Touching positive (+) probe of multimeter to “A-2” terminal of relayreading.the junction box toshould give 24 Voltshould give 24 voltshould give 24 voltshould give 24 volt4-48
