I still say he need *only* 'characterize' a portion
of the conductors in whatever beast of an application
he's got - and use that as the 'current measuring
apparatus' as opposed to the seemingly unwieldly
task of 'breaking' a high current circuit.

I have usd this trick before to measure starter
current draw on a car - first apply something on
the order of a 10 Amp load and record the voltage
drop across a convenient portion of 'exposed' high
current cable.

I have even used small needles to puncture the
high-current batt cables at convenient points for
"unobtrusive" and "non-invasive" measurements ...
