If anyone would like to know what the solution to this was, it was pretty simple. I had to add a white common wire to the system. Was using the 6/2 that was already there. Both black and white were used to heat up the main breakers so no white was available. We added a white wire outside the system to test and that was exactly what the problem was. I ordered another 250 ft of 6awg white wire and am adding in separately to the system. Except for having to dig 230 ft of ditches again and adding 3/4" conduit for the common wire, it's all good now!!!
