First things first, the infamous green wire doesn't go anywhere, it's just there.

As far as charging, they don't start charging until high revs, over 3K so if you pop the battery out, it will stop.

A voltmeter across the battery should read 14-15 V at 5K rpm, if not it'll never charge. Most likely the rotor is shorted, should be > 4 ohms across the rings. Next most likely is the regulator and then the stator. The FSM has good info on testing the whole thing.

And yup, that is the signal blinker.
