Okay, replaced the fuse, and it works just fine.

Hugo said that pretty much the only cause for a blown fuse there is a misaligned connector. So, I must have plugged it in wrong.

Tip for the wise: remove the hard drive & cable completely before testing this, so as to get unobstructed visibility of the connector before reattaching the cable.

Now.. to look at adding dimming capability to Hijack for these.

Cheers
