High Charging Rate. Found Voltage Drop Need Guidance Please

O.K. that was the condition when I got the 21.6 ohms measurement. Sorry I don't follow or understand what you mean by "infinite resistance" and no connection to ground. Does that mean in the above "safe" condition the ohms reading should actually be zero? I'll draw the sketch first thing tomorrow. Thanks for your input and patience. Have a good night!
Here. we can prob work off of one of my generic 60s schematics for the concept.
