Does the new stator have the same resistance measurements as the old? If so, the old one was not defective.
Are you sure that you are testing for output properly? Or wiring the stator into the harness properly? When you rotate the crankshaft, the magnets should cause current to flow back and forth across the windings. Measuring across red to red and then black to black you should get a voltage created. If you are measuring across there, I stand corrected. The stator will put out alternating current, which is then either fed to the lighting system as raw AC, or fed to a rectifier/regulator that will be used to provide the 12VDC+ that charges the battery and runs accessory items. The two circuits are separate. If the A/C has one lead of the stator grounded, then the other lead can go to the light switch, or be fed directly to the 'headlights' as some do now, running the lights all the time that the engine is running. If neither lead is grounded, the circuit would go directly to the load, across the headlight terminals, or be routed through a switch. It would connect to nothing else.
In most schematics I have seen, one lead from the stator windings is connected to the frame, i.e., ground. The other lead goes to the rectifier and/or headlight circuit, respectively. That saves the expense of providing a separate wire to complete the circuit.
