I have a 200 amp aluminum direct burial cable running about a 1,000 ft, which powers a pump. At the meter we have 110 volts on each leg and 240 volts between legs. At the pump I have 110 volts on each leg and 0 volts between legs. Of course the pump does not run. I assume this is caused by the insulation being removed by a rodent. How do I find the exact location of my problem?
