    . Pin A/J of the electrical connector of the lighting controller (16LF) and pin A/2 of the main panel and pedestal integral-lighting potentiometer (17LF)
    . Pin A/K of the electrical connector of the lighting controller (16LF) and pin A/3 of the main panel and pedestal integral-lighting potentiometer (17LF)
         a If there is no continuity:
  • Repair the related wiring.
         b If there is continuity:
Subtask 33-13-00-810-061-A ** ON A/C NOT FOR ALL
G. The integral lighting of more than one instrument connected to the same pulse width modulation output does not operate.
   (1) For pulse width modulation output L:
  • Do a check for continuity between pin A/L of the electrical connector of the lighting controller (16LF) and the first terminal block, ASM 331301.
     (a) If there is no continuity:
  • Repair the wiring.
     (b) If there is continuity:
  • Do a check for a ground signal at pin A/Y of the electrical connector of the lighting controller (16LF), ASM 331301.
       1 If there is no ground signal:
  • Repair the wiring from the lighting controller (16LF) pin A/Y to the ground terminal.
       2 If there is a ground signal:
   (2) For pulse width modulation output M:
  • Do a check for continuity between pin A/M of the electrical connector of the lighting controller (16LF) and the first terminal block, ASM 331301.
     (a) If there is no continuity:
  • Repair the wiring.
     (b) If there is continuity:
  • Do a check for a ground signal at pin A/Z of the electrical connector of the lighting controller (16LF), ASM 331301.
       1 If there is no ground signal:
  • Repair the wiring from the lighting controller (16LF) pin A/Z to the ground terminal.
       2 If there is a ground signal:
Subtask 33-13-00-710-051-A
H. Do the test given in Para. 3.
