The wire that winds up attached to the stud on the alternator will be the output, carrying 40+ amps.  Originally, that would have
been the yellow wire, but my suggestion is to not try to reuse the original wire as it is only designed to carry 25 amps or so;
while even a "mini" alternator will put out almost twice that much if the battery is down.  Any auto parts store should have a
smallish roll of yellow wire in 10 AWG stranded (or better yet 8 AWG) at a reasonable price; that will be better able to handle the
full output of the alternator.  And it will be much easier to install a ring terminal (to mate with the stud on the alternator) with
nice fresh wire instead of that 60 year old stuff.

mtr

Where the old control box was, you'll need to separate the small yellow wire that runs into the harness from the larger yellow wire
that originally ran to the generator.  The small yellow wire leads to the warning light on the dash.  With the alternator, it will
need to go to the separate 'L' terminal on the alternator.  You can use either the original yellow/green or original yellow for that
purpose, as the current is very small (just enough to run the light on the dash).

Are you sure the heavy yellow wire is spliced together with the brown/white and brown/blue wires?  Many of the instructions on the
Internet say to connect the yellow to the starter solenoid, which will bypass the ammeter and cause it to never register charge.

There is something to be said for that configuration actually, since the stock ammeter is only designed for 30 amps.  I chose a
different route, and added a shunt on the back of the ammeter to handle part of the current.
