I bought two 483VA amveco trafos off of fleabay. Problem is, wiring is different than what i am used to and i can't find wiring diagram anywhere. It is 0-100-120 primary, 18VA@10A, 24VA@8A (30% cycle duty), 36VA@6A (50% cycle duty).
Two concerns are wiring layout and size. None of the color coding matches any of their or anybody elses current scheme and wire seems awlful thin for so much current. I believe the primary is wired as follows:
Black - 0
Brown - 100V
Red - 120
Orange - 0
Yellow - 100
Blue - 120 (I have green and not blue)
Secondary
Green (this and red below are much larger ga. wires than all the others)
Red
Blue
Brown
White
Orange
Is there any way to test the primary and secondary wires?

Aren't the primary and secondary wiring codes listed on the label?

No.
Simplest way is to power it up and look for AC voltages on secondaries.
A resistance check will show which secondaries are connected to which.
OK.

An AC wallwart or small filament transformer (or Variac) can make this less exciting than using the mains AC.
