I'm using a 80amp regulator with 2 hho generators with a 30 amp fuse, which I'm were I need to be HHO wise without blowing fuses. My problem or question is, I keep blowing fuses to my pwm I hooked up. I know something is grounded but where? Also I have a 40 amp regulator piggy backing off my 80amp regulator. Does anyone think I'm wrong doing this and should I re-run all my wiring separating the two?
