running on no power and solution is producing a little voltage

[mytoyotasucks]

ok hate to start new theads with near same ideas.

but since i started useing a diff chem, and getting bigger bubbles, its still producing less amount when no power is on, but a 150F
and the more i run it the less amps it uses and looks like more production.

is this typical??

begining amps is 15.5, and after running 45 minutes its 9.7 amps.

and when no power, it reads .07 volts, and no power leads on.

is it a heat thing??

I think it is a meter thing.
