Unhappy ZX12R stator coil or rectifier problems?

Hi.
Is there anyone who can help me if my bike is okay, or just on the way down?
It started with a melted plug between the stator coil and the rectifier!
I just connected the wires (without a plug) and started testing according to the manual.
The stator resistance is about 1,2 ohm measured on a 0-400 ohm instrument on all 3 circuits.
The output from the stators is about 78 VAC on all 3 circuits (open circuit and around 4000 rpm), and the output from the stators is about 12,5 VAC on all 3 circuits (closed circuit and around 4000 rpm) when the rectifier is connected.
I think the wires and the rectifier turns hot while running, but I dont know how hot it normally should be?
I havent measured the power from the rectifier yet, but does anyone know if this is normal, or is it the stator coil or rectifier which is about to be broken?
Anyone who can help?

Do some regulator diode checks as I've seen them give out 13+ volts and still have a bad diode, which does make everything work harder.

Regulators do get quite hot anyway.

For Tech Questions Bike Model letters are more useful than saying the year, for uk owners anyway, as registration year is not always year of manufacturer model.
