I ask because a lot of electronics make connection to ground to complete the circuit. Maybe a ground wire from battery to jump point?

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.
