Removal.  Refer to Figure 7–1 and the following instructions  to  remove  the  relay  panel  and  field  flash  switch. (1) Tag and disconnect leads from the relay panel and the field flash switch. (2) Remove the nuts, washers, and screws that secure the relay panel to the control box. (3) Remove the relay panel. (4) Remove the locking nut that secures the field flash switch to the relay panel. (5) Remove the field flash switch. b. Cleaning  and  Inspection. (1) Clean the field flash switch and relay panel using a clean lint free cloth to remove any accumulated deposits. (2) Inspect switch contact for corroded or burned terminal. (3) Inspect  terminal  board  for  cracks,  breaks, corroded terminals, or other apparent damage. (4)   Inspect   relays   and   resistors   for   signs   of overheating or other damage. c. Testing. (1) Refer to figure FO-2 for resistor rating. Use a multimeter  and  test  on  the  appropriate  resistance  (ohm) scale. (2)  Test  the  field  flash  switch  for  continuity  while d. Repair. Replace a damaged or defective field flash switch or relay panel. e. Installation. (1) Position the field flash switch in place on the relay panel and secure with locking nut. (2) Position the relay panel in place in the con- trol box and secure with screws, washers, and nuts. (3) Reconnect  leads. 7-5.  Current  Transformer  (CT)  and  Resistors a. On-Equipment   Testing. (1)  Disconnect  the  current  transformer  leads  and remove the three resistors. Never  disconnect  the  leads  of  a  current transformer, either at the transformer or at a meter  connected  to  the  transformer,  when  the equipment  is  energized.  The  three  resistors used with this equipment are connected across the   secondary   windings   of   the   current transformer and they ordinarily prevent an open circuit condition. But, if a resistor were to fail and    then    the    secondary    were    to    be open-circuited  by  disconnecting  its  load  (the meter), extremely high voltages would be induced  in  the  windings.  Serious  damage  to  the equipment and possibly the death of personnel could  result. the switch is held in the closed (ON) position. ^- Change 9 7-3
