What voltage direct from Alternator

[CBXBob_imp]

Hi, I have a charging problem, it's actually on a CB900 but I'm thinking that the charging systems will be pretty similar.
All the yellow wires from the generator check out as per manual specs, black and white wires also fine, but only getting 14.5 volts A/C out of each wire when using AC volt meter between single yellow and ground. No volts coming from Reg/Rec so thought that was faulty, I've replaced it with a new one and still the same results.
I always thought that un regulated you get about 30 volts AC from the generator
Thanks for any input

The AC voltage is checked between the yellow wires and is around 28 to 30 volts,if I remember correctly.
