Suggest circuits for linking an analog amp gauge to the output of a 200 amp auto

alternator for measuring output under load. ? links ? commercial units ?

I once used a length of copper wire, computed resistance to wire table.
Worked for my test.

Yes, so have I, but I'm sure you know, the problem is the resistance
varies with temperature. Your current has to be low to avoid heating the
wire.
