DC motor as generator?
So I'm trying to use a small DC motor as a generator (wind powered) to charge small electronic devices, cellphones etc. I hooked my multi-meter up to it and drove around in my car. I keep getting solid voltage readings with it, up to around 10V @ 50mph, but I cannot get a current reading at all, no matter what setting I use on my meter, and no matter what speed I travel at.
Why can I not achieve a current? What can I do to change this?
thank you

If you are connecting the current meter across the generator output, that means the current is too low to measure on your meter. What current scales are you using?
Is the DC motor a permanent magnet type? If not, that can explain your problem, it is just not working.

Try appling a load with a flashlight light bulb.
You have to take current reading in series with a load.
