Troubleshooting Recommendations:
- Set the FLOOR light switch to ON on the COCKPIT LIGHTS (INTEGRAL) control panel. Perform voltage check as follows:
For the LH floor light (DS41):From To Expected Result Result TBD3715 Ground +28 VDC For the RH floor light (DS42):
From To Expected Result Result TBE3707 Ground +28 VDC - If there is no volatge, go to step 4.
- If there is volatge, continue with next step.
- Replace the bulb of the unserviceable floor light and perform the operational test.
- If the floor light operates, do close out.
- If the floor light does not operate, continue with next step.
- Replace the applicable floor light and perform the operational test.
- If the floor light operates, do close out.
- If the floor light does not operate, continue with next step.
- Disconnect the applicable floor light (DS41 or DS42) and the INTEGRAL & MISCELLANEOUS LIGHTS COCKPIT CONTROL PANEL connectors (AP26P1 and AP26P2).
- Perform a continuity check between the pins of the FLOOR LT STN 225 LHS connectors (DS41) or FLOOR LT STN 225 RHS (DS42) and INTEGRAL & MISCELLANEOUS LIGHTS COCKPIT CONTROL PANEL (AP26P1) or INTEGRAL & MISCELLANEOUS LIGHTS COCKPIT CONTROL PANEL (AP26P2) as follows:
For the LHS floor light (DS41):From To Result DS41-TBD3715 AP26P1-20 DS41-TBD3717N GS560 For the RHS floor light (DS42):
From To Result DS42-TBE3707 AP26P2-20 DS42-TBE3708N GS557 - If there is no continuity, repair or replace the defective wiring as required and do close out.
- If there is continuity, continue with next step.
- Connect the applicable floor light (DS41 or DS42) and connect the disconnected connectors AP26P1 to LHS floor light and AP26P2 to RHS floor light.
- Is the fault still present?
- If NO, do close out.
- If YES, continue with next step.
- Perform the troubleshooting for observed fault COCKPIT LIGHTS (INTEGRAL) CONTROL PANEL MALFUNCTION.
- Do close out.
