I'm trying to find out how to solve for the Thevenin equivalent. I tried to use a 1A test source, but it didn't seem to work. Anyone can help please? Much appreciated.

I would connect a voltage source to the output and use Vout = 0 and Vout = 60 to simplify the problem.

You'll get Iout = -20A and Iout = -14A, so the output resistance is 10Ω and the open-circuit voltage then must be 200V.

Below is the calculation for Rth using test source method.Vth you can try

yourself .Please let me know if you need any support for calculating Vth.
