L-1011 Trainer Installation: Indicator Light Test Circuit

The L-1011 has a "TEST" switch on both the Pilot's Light Panel as well as the Flight Engineer's Light Panel. The "TEST" switch is used to turn on all indicators and annunciators in the respective panels for testing. The circuit has a 5 minute timer that disables the test relay after 5 minutes.

The video above shows the current build-out state of the overhead panel. The TEST circuit at the moment only activates the switch state indicators and not the fault indicators. The fault indicators need to be triggered by the computer as part of the TEST feature.

L-1011 CPT - BRT/DIM Light Bus Test

Here is a test of the DIM/BRT Annunciator and Switchlight bus. The switch light used for the test is the IDG Disconnect Switch. The LOW PRESS indication is for the oil-pressure in the IDG. Anyway, annunciator power comes from Circuit Breaker CB3G16 which in turn receives power from the DC Essential Bus.
