These resets can be maddening. I've had resets go smoothly where I got it to work on the 2nd try and others where it seemed to take 20 minutes and endless tries. I've used copper electrical wire and all different ways of grounding the second wire (19). Personally I think it has less to do with quality of the "ground" (which is what the 19 pin is and the battery terminal can substitute for) and more to do with the OBC's sensitivity to the time duration of the reset. Seems like you need to get the timing just right. I've got a change coming up and I'm contemplating getting a Peake tool to make the process easier.
