Figure  13-25.—Relay  tester  assembly. Relay  Tester  Assembly The relay tester assembly (figure 13-25) provides the facilities for testing each type of relay used in the DFCS and the CSCPs. Relay sockets are provided for 8-, 10-, and 16-pin relays. The rotary switch is used to select  the  appropriate  relay  coil  voltage.  The  toggle switch is used to energize/deenergize the relay coil. The indicator lamps indicate the state of the relay under test (ENERGIZED/DEENERGIZED). Fuse Tester Assembly The fuse tester assembly (figure 13-26) is used to test fuses for continuity. The POWER ON PBI is used to apply power to the fuse tester. The POWER ON indicator will light when the tester is on. When a good fuse   is   placed   across   the   contact   strips,   the CONTINUITY INDICATOR light will come on. A blown fuse placed across the contact strips will not light the indicator, since there is no current path through the fuse. Figure  13-26.—Fuse  tester  assembly  (DFCS). 13-32
