Well finally got me dry cell built thanks to Painless, Stu, and a lot of others with your ideas. Have 11 plates, 2 1/2 X 10 1/2 with 2 X 10 exposed to the electralite due to the 1/4" gaskets. Have them set up +nnnn-nnnn plus. My plus key quit working, dog gonnit. Anyway with it on my 01 Dodge Cummins it's producing 2 liter in 55 seconds at 30 amps. Just got it installed today so it'll be awhile before I know if I'm doing any good or not.
