Possible glitch/bug/id10T operator error with transformers

    i'm having issues with the transformers.


    i have a wiring config as follows: mfsu>mv transformer>lv transformer>machine row.


    in front of the medium transformer is a induction furnace and on top of the transformer is a massfab(w/redstone signal to turn it off)
    my problem is this: when i place the massfab on top of the transformer, the machine row no longer receives power, nor does the induction furnace. however, once i remove the mass fab, everything works fine.
    i've checked and the mass fab is not running.


    here are some pictures to help. they are hosted temporary, so the links will break eventually.

    It took me a good thirty minutes to realize this, but your redstone signal powering the massfab is also powering the transformer, turning it into an MV->HV transformer. Redstone signals can go through blocks. Try having a redstone torch shine onto the massfab instead?
