well yesterday I bit the bullet. I have had my Seigrene Diamond Cell complete with reservior, scrubber, secondary bubbler and powered with 8 gauge flexible copper car stereo wiring complete with 80 amp Isolator/relay with 40 amp auto reset breaker and backup 50 amp fuse installed for several weeks but hadn't added any electrolyte. I was afraid of it freezing. Well yesterday I put in 3 quarts of distilled water and two slightly heaping teaspoons of KOH flakes. I found one slight drip at a hose clamp and fixed that. Then I powered the unit up with no way to check the amp draw. It was air locked at first so I turned it off and went for a drive of about 10 miles. When I returned home I powered it up again. The 1/2 inch return line to the top of the reservior started flowing and kept getting stronger. It was obvious that I wasn't pulling 40 amps but I didn't really know how much I was pulling. Another thing puzzled me. When I removed the cap from the secondary bubbler I didn't see any bubbles. I made up a soapy water solution and checked the two fittings above the fluid line on the reservior to see if I might be leaking gas and I also checked the top fitting on the scrubber. No bubbles appeared. Scratch head. Well today I drove to Memphis to my youngest son's house. It is about 125 miles away. After getting there I opened the hood with the motor and cell still on. The unit was still making a lot of gas but I noticed bubbles and white residue on the check valve on the side of the scrubber. I said well I'll deal with that when I get back home. We went to Sears and I purchase a clamp-on ampmeter. When we returned to my son's house I started the truck and turned the cell on. At first I was reading just over 28 amps and little by little the reading crept up until it was almost 35 amps and then it began going back down and settled around 34 amps. Tonight I drove back home and when I arrived I left the truck running with the cell on and checked the amp draw. It varied from 32.4 to 32.9 amps and there didn't appear to be a leak around the check valve. I removed the cap from the secondary bubbler and it was bubbling like crazy. It seems the check valve must have been leaking all along and simply seated itself. I turned the truck off and removed the reservior cap and inserted a Kodak color thermometer and after one minute it read 93 degrees F with an outside temp of 41 degrees F. It seems this unit is running cool and the amp draw is very close to 30 amps. That had been my target current draw. Now I've simply got to start keeping very good records of my fuel economy. I'm not sure how much HHO I am making and really am not concerned about that at present. This cell was assembled according to Seigrene's instructions and will do what it will do at this amp draw. My concern now is just how much improvement can I get at this amp draw. On my 06 King Ranch 6.0 PSD I believe my alternator can handle this load but don't want to push things any further. I'm afraid it would necessitate a bigger alternator to go further in amp draw. Well that's all I can truthfully say for now.
