You need three things to make this system to charge. 1) Stator output between 24 and 30 volts AC checked across the wires from the stator.
2) The regulator/rectifier has to be well grounded. The engine has to be grounded to the frame as well. ( Had one giving me fits until I found a bad engine ground strap.)
3) Battery voltage at the middle terminal on the voltage regulator. One volt lower than the battery is the max for it to work.
You did not tell us what the motor is being used on. I am most familiar with them on the older JD lawn tractors. The biggest cause of charging trouble was either the key switch being bad or the plug on the back of it corroded where the voltage regulator did not get battery voltage.
I worked on these things for many years I only saw maybe one or two bad stators. Never had a flywheel bad. Switches where the most common issue and then regulators after them.
