Gyro Smoking

[PhilBot]

I just tried our KOP Gyro (fresh out of the bag).

Ours also got hot as soon as I plugged it in.

As an experienced electronics guy, my nose is sensitive to "hot" smells, so I caught it pretty soon.

I checked the wiring at both ends, and went back to the online docs.

No clear reason for the heat. (Wiring looks clean & polarity was correct.)

I tried it again (double verifying plug polarity) and it still gets hot (almost too hot to touch)

Doesn't seem right. So I went looking, and found this thread.
Ours wasn't mounted at first, so it's not a chassis short.

Anyone else have ideas?
