This is a potentiometer and it has three wires:
-the first wire is called the voltage reference wire and it should be 5 volts which is supplied by the computer.
- the second wire is the ground wire and it should be almost 0 volt ( ground voltage)
between the voltage reference and the gound wire is the resistor, it should be between 0 and 5 vots depending on the point tested.
This voltages vary because each coil is an electrical load with the next coil.
