Are you using a digital multi-meter (DMM)?
It's probably phantom voltage.

I get a higher reading from 100 foot of wire run underground before I have hooked it to anything on either end.

The DVM is giving you a voltage reading that is not capable of sustaining amps. Phantom voltage, or as we call it A GHOST.

i don't know what are you working on. usually when i test voltage, if there are no voltage the digits changes, but if you have a voltage it should stay, for example you have 12v it should read 11. something to 12. something. if you're sure it is 12v try use a car light bulb or 12v power tester. 12v won't kill you, but it is safe to have it turned off.
