Hi, can you please clarify a couple of things so that I understand what you were seeing?
with the fault inop switch trying to trigger
I don't understand what you mean by this. The only thing. I can think of is that you were also getting a FAULT light on the fire panel, is that right?
Also, was the overheat only on the left engine or was it on both as suggested above? Like. Nitpicker says, parameters may be normal.
