I was under the impression that you were supposed to supply a seperate power source for the smoke pump?

I just read my instructions for the super smoke programmable pump, and it says to provide a battery supply of 4.8V, 6V, or 7.4V Li-Po................9.6V ?

Run a seperate power source JUST for the smoke pump, NOT through the expander and let me know what you get, I'm guessing\hoping that will solve the issue ....or am I mistaken? ....... Greg
