wireless controller confusing fix

RJMaestro:
re-checked everything. All is OK. No bad grounds. No broken wires. Voltages all check out.
Just to clarify. The multi meter is not in physical contact with any thing only placed near the
receiver and the wiring and then the plow works. The meter only needs to be in the "on" position.
I believe the meter is intercepting the signal from the transmitter and amplifying . I'd like to know how and why this happens and if there is a electrical circuit I can build to replace the meter permanently. It is a 12 volt system. Thanks again. Any help is appreciated.

You really need to help us.

We need pictures of the snow plow and the clamp-on meter.

We cannot diagnose what we cannot see.
