so i went to see the fried controller today.
on careful inspection, the guy had fired it up with only one, maybe 1 and a half, of the xt 150 phase plugs connected
i think they had become disconnected when he moved the bike to his place with a van, and as the bike is still only partly built, the phase cables were loose on the swingarm and the pedals(no chain yet) probably spun and knocked the cables pulling the plugs.
so basically he tried to give it full throttle with only one phase plug connected, the other was partly pulled out when i saw it and the third was loose altogether.
on opening the controller one of the banks of fets is obviously where the damage hit, 10 fets corresponding to one phase wire.
(there are 30 fets altogether)
would it be ok to replace the 10 broken fets or is it essential to replace them all to make sure they are consistent?
the pcb and other components look to be in pretty good shape still, just soot flared over them.
