This is a shot of my homemade 12V gen-set.
I don't know to HP of the diesel but I can get 100 amps out of the alt.
The motor was on a wacker brand vibratory plate that I bought at auction. I used the wacker rubber mounts and built the frame. The alt is a 108 amp Leece Neville brand.
The only goofy thing is the motor uses a hand crank to start.
