so Ive been running my prototype HHO dry cell for about a week now and all of a sudden the amperage it pulls is like HALF and its getting HOT(not the electrolyte, the plates themselves, all of them). With my PWM I maintained about 13-14 amps for the week with the PWM at about 60%. when the issue happened, i turned the PWM up to 100% and could only pull about 8 amps!

This cell is 13 SS switch plate covers with 1/16th" rubber gaskets in between so -nnnnn+nnnnn- 3quart resevoir, 30 amp PWM, 15 amp relay, 30 amp ammeter, 30 amp switch 1/2" hoses, secondary bubbler, 3/8 in and out ports

anyone know why this is happening? i Havent had a chance to figure it out cuz ive been stuck working like NONSTOP lately
