Have you ever had an aircraft problem that you just could not figure out? I doubt there is a mechanic out there that can say"no".
If you're beat down to the ground getting your head kicked..... post your problem here. Maybe someone can help you out.

Help, I’m getting my ass kicked.

For the life of me, I cannot remember how the EGT thermocouple gang does it’s job. There are 4 probes in parallel all connected to one output on a CF6-80C2. If one probe is removed from the equation, does the temperature indicated go up or down?

Thermocouples create a millivolt output in relationship to heat. If you loose a probe or section..... the output will be "less". Your temperature indication will be "lower" than what it should be.
