Superimpose current into another circuit line?

Small hand wound wire coils Transformer for induction higher current use of secondary , 60 turns to 1 turn step up ratio, with iron core is an inline wire of another much lower current circuit of higher voltage. As I understand it, an output of a secondary requires a completed path through a load for the secondary BOTH END WIRES to work. Do I assume a proper polarity blocking diode should be mounted across to ground by load resistor and to 2nd circuit , for a completed path for that secondary side? "2008 reference commented only saying I know that it seems not likely to work, but it does." The meter readings deduced that a resultant reactance ohms was induced into primary side , reducing IT'S current by .4 when other pulse applied on secondary side, with slight increase visible current on that pulse side. Voltage was reduced on the 2nd pulse side also. 12 volts DC 20amps reduced to 12 amps, then used. I don't have AC low voltage low frequency power source to test this. The only data important here, not power loss, is whether a slight current increase can be achieved in a 2nd circuit to load, as they stated from 2008. Need to know or comments please.

At the very least, it seems to me that the TS is giving us the third chapter of the story. That is, all of the context is missing.
Drawing a circuit for us will help, or at least a description of what is supposed to be happening. I am not able to see into other folks minds to determine what they are thinking about. It is a severe handicap, for me.

I recall seeing such a description that was translated that way due to language differences. Since common ground does exist then,
We can define terms that use the latest accepted science: Accepted laws of a reputable source have already been proven and are difficult to disprove.
Each statement stated in link below is true and can be used to describe an AC electrical event within the boundary conditions of a closed system.

OK, It sounds like the TS is describing a step-up transformer and asking about current flowing.
The answer is that no current will flow without a circuit (path) for it to flow thru. Certainly a voltage can be present if there is no path for current flow. Iam not sure where a diode fits into the conversation.

It may also be, based on the thread title, that the TS wishes to add a signal to an existing circuit.
