Ernest,
The Suzuki AC Generator is 400 W @ 5,000rpm, the ( no-load) voltage is 70 V 
(AC) @ 5,000 rpm regulated to 14-15.5 V @ 5,000 rpm.
I thought Amps was Watts/Volts ( 400/ 70 = 5.71) but that doesn't appear to 
be case here, what should I be dividing the 400 by?
I figure it must be about 30 amps as that's the main fuse
