Many textbooks derive the small signal output impedance of a common collector amplifier by short circuiting the small signal input and adding a source to the small signal output. Fair enough...
However, I was trying to use a different approach based on Thevenin's theorem by setting all independent sources to zero and measuring the impedance seen at the output but it seems to not work. Why?
Edit: I've attached the model I was using below...
