how many alternator amps??
Just a quick question whilst I locate my workshop manual, does anyone know how many AMPS the standard GS750B alternator and shindengen rectifier puts out please??Regards,

And please nobody start trying to do 3 phase calculations

Thanks for the replies everyone, I figured it was around 13-16 amps
I am just playing around with some custom wiring looms at the moment and I wanted to make sure I dont under (or over) estimate my needs.
I am installing a dual relay to the high and low headlight beams but I have also converted my instruments and indicators + stop/tail lights to custom made LED board's as well
Just wanted to be certainRegards,

According to Mr. Tesla, P = 1.732 I V ( where I is line current, V is voltage between stator leads, and P is power), so your stator is pushing out about 350 watts if you have 15 amps and 14 volts? double wow!
You should remember the KISS principle.
14 amps DC at 14.5V is 203 watts. no sqrt(3) required

LMAO 11 ampres at idle?? I can smell your battery cooking from here
What and how -- exactly --are you measuring this electrical value?
This is old history
