So I was able to temporarily hook this up and test it today. However only 1 of the compressors is running. 

I’ve attached a diagram for some diagnostics help.

On compressor 1 on the control board the black wire goes to the right side of the capacitor 

And compressor 2 on the control board the yellow wire goes to the left side of the capacitor.

Could compressor 2 wire be on the wrong side of the capacitor??  I wired it the same way as I took it apart with all new capacitors.

Here is the wiring diagram from my unit, hopefully its the same:

It appears that it’s wired correctly unless the wires on the capacitor need to be on a specific side of the capacitor??  Or does it not matter one side or the other

Also does the board need 2 grounds one for each compressor??  Or does it share a ground meaning of one is hooked up it’s good to go??

The ground should not affect the motor running however the board may use it, not sure. You could use you meter to see if you have continuity connecting the grounds. I am trying to remember if mine had both of the grounds hooked up to the board or not but cannot remember to tell you the truth.
