using an old car alternator for ENERGY!

SWEATING FOR POPCORN!
normally for a bike generator DC permanent magnet motors are used that is quite expensive. An old car alternator is much cheaper option. Here is my first try for powering a lamp (sorry for a bit shaky video).

The difference is alternator needs to see 12V for starting up because it has not magnets inside.
Here is my wiring up:

how did you wire the alternator up? did you just simply go from alternator to inverter to the bulb?
Unfortunately it is not so easy. wiring depends a lot on the model of alternator. i recommend to use the one with 3 pins. i will add a photo to the post that you can see my connections. i hope it helps.
PS. dont forget to add external power source of 12v! otherwise your alternator wont start up.
