Found the issue
The conduit goes under the driveway, the first conclusion was that the trench had settled, taking the conduit w/ it, breaking the conduit and 1 wire, after digging it up the conduit was found to be intact.
After pulling the wires and inspecting them I found that the defective wire had been arcing to the conduit eventually burning itself out.
I'll run all new wire and keep my fingers crossed.
What a PIA
