TM5-6115-634-14&PNAVFAC P-8-647-14&PT0-35C2-3-445-14TM-6115-14&P/15-25.TEST SPECIAL RELAY ASSEMBLY (cont)b. Test the dc relay assembly (8)as follows:(1)Apply 24 Vdc to terminals6 and 15 then use anohmmeter to test for con-tinuity across terminals5 and 17, and an opencircuit across terminals4 and 17, and 3 and 13.(2)(3)(4)(5)(6)(7)(8)Remove the 24 Vdc fromterminals 6 and 15, andapply the 24 Vdc to ter-minals 13 and 15. Use theohm meter to test for con-tinuity across terminals1 and 14 and 2 and 3.Remove the 24 Vdc fromterminals 13 and 15.Place the ohmmeter probesacross terminals 10 and12, and record the meterindication.Reverse theprobes on terminals 10and 12, and record theindication.Resistancesindicated should be highin one direction and lowin the other.Repeat the above test,using terminals 24 and 21.Use the ohmmeter to testresistance across termi-nals 7 and 8 for approxi-mately 7.5 K ohms resis-tance.Repeat step (6) to testresistance across ter-minals 19 and 20 for samemeter indications.Apply 120 Vac to terminals18 and 22 and use the ohmmeter to test resistanceacross terminals 7 and 8,and 19 and 20.
