balance tap issue

Should I resolder the ground lead to + side of cell 4 on the Neu pack then or resolder the entire pack? The wires are layed out the same way in each tap, ground going to the slot with the arrow on it and counting up voltage each one over.

The only difference it the neu pack reads + voltage and the MA and TRC packs read - voltage.

to note, the MA and TRC packs are as they came from the factory and have never had the shrink removed or been modified in any way.

Here's what I would do:

Measure the tap wires and find which lead is your ground. Take that lead and it should go into the first slot on the balance tap. The next wire should be the junction between either cells 1/2 or 3/4 depending on how the ground is set up. Just make sure it reads +3.7V like your other packs do. Then repeat the process until you have all wires populated and the polarity is correct like your other packs.
