Thats 14g single strand wire, its common on commercial and large sites. A tone generator and probe is the tool you need. If you know what zones correspond to the wire terminal numbers in the irrigation controller just wire tone both ends. Towards the controller and towards the valve. Mark them with numbered labels as you go. Tempo Tone Generator After reconnect the corresponding valves with silicone SPLICES for direct bury like a 3M dbr. If you dont want to use DBR splices then you will want to use 12-18awg silicone filled wire nuts and put a 6 inch round box over the repair. Direct Bury Splices If you don't know your zone layout ignore the toner. Repair the wires, it doesn't matter the order. The only issue this will cause is with your programming. After repairing manually start all the zones on your controller, identify them while running, and reprogram it appropriately.
