Default Help with rotor test

I have a Honda CB 750K with a charging problem. Can anyone tell me how to test the rotor?
Thanks

If it attracts your screwdriver, and the magnets aren't crumbling or missing - it's Good.

Do you mean the Stator?

Set your multimeter to AC-volts, and read between any-two of the three yellow wires with the bike running, unhooked from the Reg/Rec. Check each "pair" (three tests). Should be ~45-60volts, with frequency and voltage varying with engine speed. Don't run it that way for long; it's possible to damage it. More volts is more better. Absence of volts or low volts on any phase = Bad Stator, and Sucks to be You.

Good Luck.

AirHawk: Re the rotor, you said If it attracts your screwdriver, and the magnets aren't crumbling or missing - it's Good.

I can just barely feel the magnetism in the rotor. It doesn’t grab or hold a light screw driver. Should it be strong? There is no cracking or crumbing.
