Fire lights illuminated when power is applied to jet

[Stickler]

In 2.8.0.32235 (did not notice/check before), when entering a cold and dark jet and applying external power, the fire lights illuminate even though the MASTER TEST switch is set to OFF.

The fire lights can be switched off by starting and unstarting the FIRE DET/EXT MASTER TEST.

I have not found any indications in the RL manuals which would indicate this behavior is correct.
