The information came from a block diag and from post #2003, mermoz92,although they refer to the possibility that breakers feeding the RAT heater breaker may have been switched of as per maint man to ensure isolation.If these were not reset other functions would be unpowered including tows.
I must try to read your Graph thoroughly after assembling the tiles,to see if it is possible to establish if RL2-5 was faulty or if alternatively there is any evidence that the sensor logic feeding the relay was erroneously causing it to be de-energized.
Apologies to the winged fraternity for boring technicalities.
