Hi all,
ok, I changed the driver motor to 1/2hp one -2900rpm-

changed the lead wires going to the cell with a ticker one.
redone the test with 5volts on the rotor
results:
USING TAP WATER
voltage droped from 22Vpeak (without cell connected) to approx 7Vpeak (with cell connected)
changed the water to REVERSE OSMOSES (containes less contaminants)
voltage droped from 22Vpeak (without cell connected) to approx 9Vpeak (with cell connected)
Do you guys think that the cell is too much for my small car alternator?
As well I noticed that if I higher the voltage more than 6v on the rotor, the driver motor would not have enough torque to speed up the alternator. Is this normal?
