I connect to the lead which would be connected to the battery ground when
jumping. I.e. I pull the lead off the battery and jump from there (although I have also clamped onto the body ground post with the same results).

I replaced the ground lead with no difference in behavior.

The positive jumper cable connects to the positive battery post.
