Ohmmeter on lower caliber. Should find ~1 Ohms or less beetween yellow wires, three identical values. Yellow wires should be isolated from white / black / iron of stator. The alternator is so weak on these bikes that except with a connexion error - short circuit...- I don't see how the three phased windings could be destroyed.
The problem should always come from the excitator winding (the little one in a cylindrical iron box at the center of the stator). Should find ~5 Ohms beetween black and white wires. At 3 Ohms, consider it's fried, with some copper turns short circuited. Your bike won't charge and soon (if not already the case) you will fry your regulator if it's the simple unprotected OEM Shindengen. Once the stator changed or rewired, to know if the regulator is fried, charge your battery at maximum with an old fashion charger, to get something like 15 V. Then start the bike and rev it at 3000 to 4000 rpm. Measure amps by replacing the main fuse by an ammeter on 10 A caliber. If it still charges, with 15 V on the battery, the regulator is fried in short circuit (excitator winding always connected). Don't ride the bike in that state : you can destroy your battery and fry again your stator. Instead, change the regulator for a modern one (Electrex, Electrosport) which has an over current protection. And consider replacing all the lights on your bike - including H4 headlamp - with compatible LEDS, as I did, in order to solve completely the problem, even if riding in trafic jams by hot weather... I ride since this spring my 650 and NEVER charged it with the charger. At the beginning, I had the small charger in my rucksack, but found it no longer necessary now. Before this electrical update, I had to charge the bike every night, and even during lunch time when riding for day trips.
