TM 1-1520-252-T 6-3.3   TRANSMISSION   CHIP   DETECTOR   FUZZ   BURN   OFF   OPERATIONAL   CHECK 6 - 3 . 3 INITIAL SETUP Personnel    Required: Aircraft Electrician References: TM 55-1520-240-23 Equipment   Condition: TM  55-1520-240-23: Battery  Connected Electrical Power On Applicable    Configurations: W i t h     Tools: Test Set, Chip Detector Fuzz Burn Off TE 145-02-5400-1 (Appx E, E-266) Multimeter Materials: None TASK RESULT 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11 12 Disconnect   plug   235P9   from   fuzz   burn-off module. Connect  fuzz  bum-off  test  set  (2)  to  fuzz burn-off  module  (3).  Connect  plug  235P9  to fuzz  burn-off  test  set. Check  That  MAINT  PNL  circuit  breaker  (1)  is closed. If MAINT PNL circuit breaker (1) is open, close it. If it opens again, go to Task 8-14.4. NOTE When the fuzz burn off test set is plugged in, the latch TEST/RESET switch is dis- abled. Connect   multimeter   to   fuzz   bum-off   test   set (2).  Adjust  multimeter   to 50VDC   scale. Turn  test  set  ON/OFF  switch  (4)  to  ON. Test set POWER light (5) shall come on. If it does not, go to Task 6-3.4. Multimeter shall read above 24VDC. If it does not, repair or replace test set as required. Multimeter reading shall drop below 14VDC and return to original reading. If it does not, repair or replace fuzz burn off module (3) as required. Verify  that  corresponding  latch  indicator  trips (black/white). Results should be the same for steps 6 and 7 at each selector switch position on the test set. Adjust  fuzz  burn-off  test  set  selector  switch (6)  to  FWD  XMSN. Press  and  release  fuzz  burn-off  test  set  TEST switch   (7). Repeat  steps  6  end  7  for  each  selector  switch position  on  fuzz  burn-off  test  set. NOTE Wait at least seven seconds before re- peating test on any one selector switch position. Turn  test  set  ON/OFF  switch  (4)  to  OFF.  Open MAINT  PNL  circuit  breaker  (1).  Disconnect multimeter   from   fuzz   burn-off   test   set   (2). Disconnect  fuzz  burn-off  test  set.  Connect plug  235P9  to  fuzz  burn-off  module  (3). Close  MAINT  PNL  circuit  breaker  (1). Set  GND  RESET/TEST  switch  on  maintenance panel  at  sta  516  to  RESET. Indicator reset (black/white). FOLLOW-ON   MAINTENANCE: TM  55-1520-240-23: Battery  disconnected. Electrical  power  off. 6-88 Change  12 END   OF   TASK
