Using an ohm meter I now see changing resistance when light is added or removed so the cell is good. Im seeing quite a bit of corrosion so once I get this cleaned uo it will probably work.It tried to work before then quit.Once I get it operational, how would one go about calibrating it. I see two trim pots in the circuit,hopefully it wont need adjusting........DAVE
