Jim, the motor you have will deliver dc volts, you have the meter on ac vots and digital meters give strange readings with dc on ac scale.
The motor should give 11 to 12 volts dc at 2500 rpm.
On your meter 20v dc would be good, from the off position 3 notches or scales turning to the right.

I did not notice the leads as i looked at what Jim asked .
But i think his generation will be AC and not DC  A rectifying bridge will be needed for DC .
 Simple test . Put output to a LeD. And turn slowly ,it should flicker.
Reverse leads and try again and it should still flicker .
If so it is AC and LeD is only using half of power generated.
If it only goes in one direction then it will be DC generated

They are mosrly all pm motors Scorp, so will deliver dc not ac, except any stepper motors which deliver a form af ac depemding on how the coils are interconnected.
