Hey KK: very impressive. A couple of questions..what is the output amperage of the alternator (90, 140 etc.) and rpm your driving it at? Does it get hot? Could you explain why you're using the light...I'm lost. Is it to pulse the negative or reduce amps in? Lastly, what is the maximum variac voltage you've put into the alternator without blowing it up? Thanks for your answers KK. Voltar
