Hi roller24
Do you have a current limiter on your H-generator? Sounds like your having thermal run-a-way problems. Go to youtube and put "zerofossilfuels" in the search engine. He has a pimer on PWM /current limiting. As winter gets here, we'll all probably have to add more elecrolyte to get the "cold H-generator" to put much HHO so a current limiter will be more and more required.
