The "stud" is irridited steel. 8mm. Now gauge that to intermittant duty starter motor studs - 3/8"x24 pure copper. Ooooo lesseee. Eight rectifiers. The largest in the industry is 50 amperes x 4 or half the rectifier bridge. With a nominal pulley speed advantage of 3x1 their comments admit at 3,000 RPM this alternator can not keep up with standard hotel loads.
My 8-9/16" Niehoff is a 400 amp unit and it discolored both half-inch diameter copper studs and blistered a finger when I accidentally slid my hand into it. A month later the newly created remote rectifier got bolted in a foot ahead of the four Rolls three cell batteries.
I posted this for amusement plus a dash of reality. It just isn't China that peddles the absurd -although their LED smd heat sinking tech borders on Larry Curly & Moe level. Google image a 4875-JA Leece-Neville and see how Prestoloite had to create exterior rectifiers to withstand high amperage.
I came across this image today and dropped my coffee cup laughing. Unbreakable and it was empty. I have to believe I am the last of a dying breed as alternator engineering meaning the real stuff has gone off shore. Keep a remote rectifier I described months ago in the back of your mind. Why? Ummmmmmmm let's see - how do we get an immense amount of amperage all the way to the batteries? (3) 6-gauge wires or one 3/0 ? Fascinating amusing.
