The resistive wire won't drop voltage without a load.

Say what? Whoever told you that was pulling your leg. With the wire disconnected there will be minimal current flow, but there will definitely be a voltage drop.

Yeah, when in the "Ohm's" mode the multi-meter puts it's internal battery voltage through the component being measured, and meters the drop accordingly. Mine uses a 1.5V AAA battery for voltage source.

And when the meter is in the DC voltage range the meter will supply the load
