Wot i don't understand is stall straps are they not on the outside of the loft, and are. the birds not being timed outside the lofts, i agree with you about open doors,
Does it have engine management light come on on dash board, its a yellow/orange colour looks like an engine? because if thats on, its gone into shut down mode, you will need it put on computor to diagnos problem, no good just guessing,
