TM 5-6115-593-12 TO 35C2-3-463-1 (1) Disconnect   minus   lead   from   KVAR meter M108. (2) Observing polarity, connect a multimeter (set to measure 0-1 miliamp DC) in series with disconnected   minus   lead   and   open terminal of meter M108. (3) Meter   reading   should   be   within   ±3 percent of multimeter reading. (4) Disconnect test equipment and reconnect lead to step (1). o.   Test of POWER FACTOR meter (15, figure 4-22). (1) Tag and disconnect all leads connected     to     meter     terminals     1 through 4. (2) Using an ohmmeter set to Rx1 scale, measure  resistance  across  terminals 1 and 2. Reading should be less than 1 ohm. (3) Using    an    ohmmeter    set    to    Rx100 scale, measure resistance across terminals 3 and 4.  Reading should be 950 ohms +20 percent. (4) Remove  tags  and  reconnect  leads  to meter terminals. p.   Test of VOLTS AC meter (80, figure 4-22). (1) Connect a multimeter (set to measure AC  volts)  across  terminals  of  VOLTS AC meter M101. (2) Meter   reading   should   be   within   +3 percent of multimeter reading. q.   Replacement. (1) Replace inoperative or defective gauges and switches on control panels as follows: (a) Tag  wires  to  gauges,  switches or circuit breaker. (b) Remove wires. (c) Remove mounting hardware. (2) Installation. (a) Mount   gauges   and   switches onto    control    panel    with    mounting hardware. (b)   Reconnect   wires   and   remove tags. (3) Removal of circuit breaker CB1. (a)   Tag  and  remove  wires  to  CB1 (87, figure 4-22). (b)   Remove bracket mounting screws   (86)   to   release   circuit breaker (87) from panel. (c)   Remove circuit breaker mounting screws (85) to release circuit   breaker   from   mounting bracket (86). (4) Installation of CB1. (a)   Install    mounting    bracket    (86) onto   circuit   breaker   (87)   with screws (85). (b)   Mount   circuit   breaker   (87)   by securing  mounting  bracket  (86) to panel with screws. (c)   Connect lead wires and remove wire tags. 4-41.  HARNESS ASSEMBLY. a.   Inspection. WARNING Set MAINTENANCE LOCKOUT switch to LOCKOUT.      Disconnect   negative   cable from  batteries.    Remove  external  power by  opening  CB101  (120V  RECEPTACLE BREAKER).  Load terminals of generator set   circuit   breaker   (CB2)   may   still   be energized with bus voltage. (1) Inspect connectors for damaged threads   and   bent,   loose,   or   missing pins. 4-70
