stray voltage?

I'm replacing an external light on the side of my house. When I hook up my voltmeter between the ground and neutral wires it shows 15V!! The original wiring here is that there's a cable going from the circuit-breaker to the wall-mounted junction box, then another cable that goes from the junction box to a wall-switch.

Just to check, I tested some outlets and as expected they all show 0v. What could be going on here?

Thanks,

Paul.

Ignore the reading. It's meaning less when no load is present.

Its a tough call.
I would turn off the power to that box and check the resistance between the neutral and ground.

ok - what would be acceptable? What would an unacceptable reading indicate?

Thanks,

Paul.

Close to zero. A few ohms would be expected. I would expect less than 5 ohms if you are careful with your measurement.
