Hi all and thanks for your input!
I was the one who tested this for axl. I have not worked much on EMs yet, but I am eager to learn!
To recap, the problem is that it blows the mains the instant I plug it in. I checked the power chord and the power switch to be ok. I checked the 8 amp line fuse to be ok. I unplugged all other fuses in the game, and although I might be wrong this should mean that I am testing the transformer without load. Power in, no power out. It still blows the mains. Once the mains blow, there is a whiff of burning smell coming from the transformer - I might be imagining this though, as I cannot trust my sense of smell anymore. I am old.
The transformer appears to be wired correctly. Norway is 220V, and the wires go to the correct lug on the transformer.
Since the mains blow instantly, I cannot test any output whatsoever. So I came up with the idea of testing the transformer for continuity. Looking at the attached schems, it seems to me that lugs 1,3 and 5 should have continuity. The same applies to 7 and 8. What puzzles me, however, is that ALL the mentioned lugs buzz. Is this how it should be? I would imagine that bank 1,3,5 would be separated from bank 7,8 - especially since the fuses in the game are removed. The lower lugs do not, however, buzz with the upper lugs 2,4,8,10 - which I guess is good news.
Am I doing it wrong? Is there an approach to test the transformer under the given conditions? I would prefer not removing it from the game.st (resized).pngtrafo (resized).png
