daft question time. Have you checked the voltage input on the regulator/rectifier rather than assuming its a generator (coil/magneto issue)? These are known to fail on almost every bike at some point.

I'm not 100% sure about the numbers but everything tested came back with consistent readings.The reason I believe its the rotor is because the bike doesn't get to 14v even while running. From what I've been told that points to the magneto/rotor as the bike is not receiving any charge?

Is is thread for an FZ1? if so prolly should be move to that section so when the fix is found other FZ1 owner can be made aware.
Test the voltage coming from the generator at the plug with the bike running, just a small rev should give you 13v plus, if not it's the stator of the rotor.

Or will it start without it connected?

I think (from memory but I could be wrong) you should be able to get at the wires through the back of the plug that goes into the rectifier.
Just edited my last post, ref Ohms testing take a look.

Jeepers mate; that's a right mess I hope you get it sorted
