on video How to Make 12v 90 Amps DC Generator from Old Car Alternator - Step by Step

 I will teach you how to use a simple diode for the self-excitation of a 12v 90 amp car alternator and therefore to use it as a generator. The brand is Valeo.

I am going to use a 12v 90 amp Valeo car alternator and turn it into a generator to charge the batteries. Also for field excitation or rotor excitation I will use a 3.7V lithium ion battery.
I will teach you how to convert a 12v dc 2000RPM car alternator to 12v ac 600-700 rpm at home and most importantly (without the use of an additional circuit or step-up converter or transformer etc. .) - Low RPM

12V 64A Car Alternator (2000 RPM) Converted to (600 RPM) - No circuitry or transformer needed.
