No, probing the two wires going to the switch should show you no voltage since neither of the two wires is a ground. You need to find a good ground to put you negative probe on then start testing the wires for voltage. And you need to check the ground wire as well. And even them you might not get a true voltage reading without pulling a load on the wires.
