You are in luck. You have a voltage deviation caused by a broken wire. The orange plate under the electronics (the one with the cable sticking out if it) needs to be replaced. One of your voltage tap wires in the cable is broken. You can try twisting the wire clockwise or counter-clockwise one turn - it might connect enough to work, but otherwise just replace the plate.
My old webpage that I took down but somebody here copied showed the process of removing this plate.
Where are you? Eli in Oregon, Eric in Denver, Matt in Arizona or Dave in North Carolina can do it if you can't.

While checking the voltages of the cell sticks on the BCM c connector they are all roughly the same, say 15.5, except cell stick pair 5. This reads zero between the grn/rd and grn/wh wires,
Now if i check red to white it reads 155 volts.
Soo, i presume that stick 5 bad. Correct? What next, would grid charge help?
