Can you describe in more detail:

- Exactly how it was cross wired (what were you doing when it happened), and
- exactly what do you mean by noise interference?

It's possible you might have just blown an external fuse, such as the one inline on the yellow wire on the back of the sled.

If you were working with the docking sled wiring when the alleged "accident" happened, maybe the cross wiring didn't actually hurt it. Maybe something else unrelated and easily fixable is wrong, like this?
