I still think what I say is valid. If your testing in DCS you have several different scenarios that can play out and two of them leave you not knowing for sure if the engine is good or bad. For PS-2 and PS-3 if an engine stays silent and doesn't add you could have a dead board. Or a board that catch watch dog and stays silent but won't add. A conventional test can rule out the dead board. If an engine misses watch dog and starts up, but still can't add or operate you still do not know if board is good or bad. With conventional test you know whether it operates or not. Once clearing that hurdle you can move to the DCS test at least knowing the board and engine fully function in conventional and having completed a reset.
As far as not loading. I am of the mine to delete engine from remote, clear any lash up it was in and than try to add. If no joy do a recover engine. Still no joy use a dedicated test track and clear out ID one in the remote too and try again. If all that fails you have to take the shell off assuming you have wired your TIU correctly and other engines work fine. G
