Now that I have some space to work I was able to get the project wired and into position for testing.

1st step was to get the voltage/current sensors connected to the Nano. I switched from the  larger wire to wire wrap wire to minimize  my soldering on the Nano chip.  Currently only tacked the a couple of pins. The rest was wire wrap.  Soldering is pretty crappy looking. Between a board that didnt take solder very will and my eye it was interesting soldering. I need a better magnifier..
