Most information I have found states 9.5 volts ac is what you are looking for. This is lower than the D.C. Output of the regulator, but the capacitors in the regulator will step it up to what should be higher than battery voltage inside the regulator. If you are just a bit lower than that than you might be getting just not quite enough voltage to charge or maintain the battery.
thanks, yes I was testing in ac volts, at high idle yellow to white was 8.5 volts, I ordered a stator and tried it when it came in, it wouldn't start with new stator, it had spark but just too weak. So I've ordered another one I'll try it when it gets here.
