I've been battling a poor running vehicle all season. It appears to be electrical. While checking my battery connections, I noticed that the negative battery terminal on my brand new Odyssey 925 will rotate about 1/8".
I removed the screw on post and verified that it is the battery terminal itself, not just the screw-on SAE top.
Here is a video:

Is this normal? The positive side does NOT move.
Thanks.
