Damn GI....
ChadTower:
Not everything routed through the recitfier board actually gets rectified. Some just gets fused there and passes through.

EXACTLY... Thank You Mr. Obvious...
More going on here than 'meets the eye' I think...
How could just quickly 'touching a screw' cause transformer damge without blowing the properly rated circuit fuse?
Toadie:
Yeah it's a space invaders pin so it's a 2518-54. It's a new board with newer components. I can't say I have all the answers as this is my first pin so I'm not sure if anything happened to the transformer. In terms of how it happened...
Took working #47 out of the top bumper (second from the left), placed a #47 back in, gave it a twist to lock it in, and pop... no more GI
When it happened I could see the metal touching the screw so I know that was it. I tested the continuity in all the fuses so yes, they were all good.
I've sent the board off to the supplier to get it tested.
Toadie:
While the board is out, is there a way for me to test the transformer?

I've seen stuff like this happen when there is more than one short. Not all shorts are across circuits. Sometimes they are in the same circuit and they just allow a different current path to do something like bypass a fuse.
