fault locate

Had a call to a house way out past Ignacio to locate an underground fault on the line feeding the well pump. Got out there and isolated the line that was faulted. Then I connected up my fault locator to find the fault location. Not good! My locator just would not stabilize and show me the location of the ground. Very frustrated and could not charge the customer for the call! Went home empty handed with nothing to show for the trip! Lost 4 hours and gas out and back! I just could not charge the guy though! He did give me a jar of salsa and a jar of peach jam! That's how it goes sometimes!
