Hi, I have two hammond 373bx power transformers. I've used hammond transformers a lot and they always work great. But now these two, both!, i wired them up to my variac, blue and white on the variac and brown and black wrapped together and .... nothing. Both won't do anything. No high voltage, no 6.3 and no 5 volt. If I bump the voltage to about 100 volts on the variac, the high voltage starts to swing between 0 and 50 volts. I don't get it. Thist is not my first time. What the heck am I missing? :/
Here is the wiring diagram:
