I am French (ok, bilingual a good Canadian)my self, all i mean is its about time somebody said that, And now people maybe are ready to listen.The world we live in makes us see the opposite of what is said or written , it's just a mater of view.I am happy you did, i did not have the balls .

Mark  , thanks for being here Nop

    I'm trying to figure out a cheap wattmeter guys believe me.  Some kinda homemade wheatstone bridge vumeter or something.

@ Sparks:

Electronics goldmine has a watt meter on sale for $19.00.  I was going to ask folks on here if this would be handy to have for our tests.  It is a Simpson (good name) panel mount meter and if you go to their site you can find it, sorry I just got in from work and did not post a link.  You can probably make one for less but, this does not seem like a bad price to me.

@ All:

I will try to respond to the many other posts after I get something to eat as I have not eaten all day.  Thanks.

Sparks, I agree with you there. A scope is the best way to take voltage measurements from this circuit. I also think your right regarding the dB meter. Another possibly more accurate voltage measurement would be an old tube type analog meter. They have about 10Meg input impedance and I'm not sure but I don't think they would be effected by frequency as much as the digital meters. You could probably pick one up at a flea market pretty reasonably. I think I still have one laying around. I guess it's time to do some tests to compare readings from analog, digital and scope.

NOP,  the circuit needs to be broken and the meter needs to be in series, period. All of the current needs to go through the meter to get a proper reading. The shunt in the meter is used for the meter to get it's reading from.
In a parallel circuit the voltage across the branches of the parallel circuit are the same. What is different is the current. To get the total current, you add up the currents flowing through each branch. This is why the meter needs to be placed in series and not in parallel.

Sorry to keep harping on this but if these measurement basics are not followed, your results will not be right.

   You Definably know more about Magnetics than i do . Am i not using Eddy Currents in My Piggyback coil to get the overunity i get ? From the welding rods i mean . I don't have them glued or coated and i get very high magnetic effects from the rear of My coil .I didn't follow Bedini's instruction like he said to the letter . i used variables and what i had .I ended up with purring kitten that is soothing to my ear . It runs no matter what. Short of the battery frying . I know its off topic But i think it could be Valuable information . kinda like winding a joule thief on welding rods ..
