So am I correct in reading that the fuel contents gauge and the amber contents warning light are working off the same signal input, but the red low contents warning light is independent from them?
So, if unknown water contamination has taken place, a red light alone might have been incorrectly seen as a spurious warning where the gauged fuel contents appear sufficient and the "early warning" amber light has not yet illuminated?
Yes, having read it again, I think it does mean this. Normally crew are trained to look for confirmation of a fault or caption by looking at a gauge, or vice versa. It appears that this is potentially a very hazardous thing, especially if only a few drops of water can seriously affect gauge accuracy.
