The neon tester turns on with as little as 90 volts, maybe not enough to operate a motor device but a lamp should turn on.
Find the circuit in the panelbox and the wire that exits. Trace this as best you can along the joists and see where it goes up in the wall. Then determine what room it is in and go from there. It may go to a switchbox first, make a splice then go to an outlet in the room - or - it may go to an outlet first then is daisychained to the next outlet and so on, then maybe go up to a switchbox.
Wiring can be frustrating, just take your time and reason things out.
