If a ribbon was "off by one", -12V would short to ground. That would certainly be a problem. But it seems like if it happened in two rack cases, the problem is at the module end of the ribbon. Check that right away to rule it out.

What module is it Is it new Have you used it before

I have a G3 as well, and I tested each module that was in the G6, and they aparently survived whatever happened. Happy happy (I was really cold sweating there for a while). Except for one module, maybe. When I installed it in the G3, the same thing happened, and now I'm a bit short on power on the Eurorack side of things :-/

If the G6 and G3 are easily fixed, I would like to know it. Also, I'd like to somehow test the module that appears to have caused this, if it actually is faulty somehow, or if I just screwed up.
