I've built a wind turbine which i hooked up to a small generator i bought off ebay for $20 bucks, and it didn't specify how many RPM is needed to produce sufficient electricity. So im wondering if there is a way to test if the two positive and negative wires coming out the back produce an electrical current. Does any one have any ways to check if it works? But i don't have one of those voltage meters which you measure stuff like that, so are there any alternatives? Please help. All answers appreciated!!
thanks
