Hi,
Couple things. Every instructions I've ever seen for attaching these battery cutoff devices has been to attach them to the negative terminal. The size of the clamp matches a NEG post which is smaller. Further, these devices usually have green wheels.. a common color used for NEG terminals as opposed to red for POS. Instructions for removing cables from batteries always suggest disconnecting the NEG cable first. That is not to say that there isn't a lot of negative information floating around out there (pun intended), but is sure seems very common practice. More opinions welcome.
In my photo, I have a group 47 battery (not the correct battery). The green cutoff device is connected to the NEG post on this battery, not the POS post. I think you are concerned that my POS post would be arcing to the side of the battery box, but that is not the case. This could be another good reason for having the cutoff device connected to the NEG post.
