pictures.

It looks like a brushed DC servo machine.
The amps are probably usable, unless they are the part that keep failing.

Peter,
Thanks for the info. It might just be the problem. I am waiting to get
access to the machine and then I will test all the advise I received
here. I will give feedback on my findings.

1. Does this machine have Trak sensors? These are devices that ride
along the table (X) and saddle area (Y) and have cables that attach to
the system. These are electronic Trav-a-dials.
2. These systems were very popular back in that time (late 80's early
90's). The motors are brushed DC servos.

Jon Elson has one of those for demos. That's a really good mill for
demos. Not sure it's so great for doing any work. I always thought
I converted one of these. Adding CNC to it just automates junk IMHO. I
would say after you convert it, its 'average' but I'm glad I got rid of it.
I sold it, and for not much more than I sold it for, got a used BOSSV with
a working original control.
