2005, FZ6:
I had the warning light come on along with a Code 46 a few weeks ago, did a bit of fault finding, checked the voltage regulator and found it was faulty, replaced it.
I charged the battery but 20 miles into my trip, same fault, turned around and got home.
Measured the stator windings and they were a bit low so got that rewound. I now have NO voltage out of the stator but the windings are all uniform at 0.8 ohms.
Next thing to look at is the magnets on the flywheel, anyone know how I can test these?
Any other pointers gratefully received.
Just think how stupid the "average" person is. Isn't it a worry that statistically approximately 50% of the population are thicker!
They'll do their best to grab your screwdriver if you wave it within an inch of them.
Modern ceramic magnets don't lose their field easily: unless they're obviously smashed, I think your problem lies elsewhere.
Where were you connecting the meter to measure the stator output?
I measured voltage across the winding pairs (and the resistance across each winding 0.8ohms, and the resistance to the body of the stator; infinity)

I guess whoever wound your alternator messed up.
Each phase has a total of 6 windings, they need to be wound in the right direction... if three are wound one way and three the other you'll get the correct resistance and zero volts.
So an update...
I had the stator checked and there was a slight short so with that fixed I got a stable 40+VAC.
So I got a new regulator and I had 13.6V output so all good.
All has been well for the past few days and I finally got round to fitting a new clutch cable.
Went for a run today, did 30+ miles, switched off, adjusted the clutch, started up, rode 20 metres and now the management light is on again.
I've checked stator output and swapped in another regulator but still only get 9.5V at the battery.
Anyone got any ideas on what I'm missing?

It's possible that you have a dodgy wiring connection somewhere.
Get a multi-meter in resistance checking mode, then clip one lead to the negative terminal whilst you use the other to trace around the loom to see if there's a point at which the resistance suddenly changes.
(NB don't go as far as the positive battery terminal unless you want to buy a new meter...!)
