EE suggested this method yonks ago on a post about battery monitors.
It requires measuring the impedance of the ground return, then using [V sq/R] = W or Ohm's Law to get the current.
Problem was a milliohm meter is not a common tool in most kitbags.
It got filed into the 'Too-hard-basket'
EE's method is valid......just hard to implement.
