Hi Dave ,
the armature test is with a AC voltage to check for shorted turns , the transformer action of the armature windings
make them show up better than with DC
yes with a variac transformer you will need a step down / isolating transformer as well

we used to use a small transformer with the lams cut open normally called a growler from the noise it made when you found the shorted turn, did not work on the 100 plus hp dc motor I used to rewind though, as the turn was a loop of copper tape 1/2 X 3/32 the other name is not politically correct now a days
otherwise it was drop tested with 2 vdc from a mg set ( we used welder cable to carry the juice )
David D did you get my pm about the amadeal board being the same as yours

As part go my apprenticeship I had to spend a year in the armature/stator winding dept at Stanton and Staveley ltd at its Stanton works so it was big old dc stuff for me :) john Swift just triggered a long lost memory from when I was 17 65 now though :)
so not so much as a unwind moment but trade talk
