Skyrangerpro, to clear that one up;
If the transfer pumps are switched off, within three minutes, the CAD bars flash, the F Pump Aft/ F Pump Fwd captions illuminate and the Master Caution illuminates. When this is acknowledged the CAD bars and Master Caution light extinguish, leaving the F Pump Aft/F Pump Fwd captions remaining on.
If the pumps are then reimmersed in fuel, the captions remain on because the pumps are switched off. If you then switch the pumps back on the captions will clear.
If the F Pump Aft/ F Pump Fwd captions illuminate of their own accord, along with the CAD bars flashing and master Caution coming on, the pump(s) have either failed or have been running dry for longer than three minutes. At this point (illumination of the cautions) the respective pumps should be switched off iaw the FLM procedures.
Acknowledging the caution will extinguish the CAD bars and Master Caution.
If the pumps are not switched off and the pump is then reimmersed in fuel, the F Pump Aft/F Pump Fwd will extinguish.
I know others will have different opinions based on flying in different aircraft where you don't have to think about the fuel system too much, but it is quite straight forward.
