Hi everybody
my name is Rudy, coming from switzerland but living in Romania.
I have a device (HHO box) that I would like to run in the car from the battery, but only when the engine is running. That means when the battery has about 13.8 V.
When the engine is off is has about 12 V. Then no current should flow.
It should with a turning knob limit the ampere, so that a maximum of (3 ... 15 ampere needed for selection) is going trough.
I am not an electric, has somebody an idea?
can somebody build one for me?
or where I can buy such a thing?
thanks, Rudy
