was having an issue with my speedo, after watching this it turned out to be the key that runs the gear. Thanks for the information saved a bunch of time.

@zx636racer A 3 wire speed sensor does have it's own key switched power supply on one of the wires (the other two are ground and the signal output). In this test, the positive lead of our multimeter is connected to the signal output wire and the negative lead is grounded.

@zx636racer. You're testing the output of the sensor. It's the same as testing the voltage of anything else on your vehicle. The red lead to the sender output, the black to ground.
