Measuring V loss during charging
I know that a discharged battery can pull down the voltage at the charger. I was trying to measure voltage loss in my converter wiring, switches, etc. The two 105 AH batteries were 12.13v prior to ...

Quote: "Measure the resistance of the circuit."
To elaborate on this: In this case the resistance is too small to be measured directly with a typical ohm meter because the current generated by the typical ohm meter is so little. Best to measure (an estimate is probably close enough) the current in the wire and the end to end voltage drop in the length of wire (as suggested above). In this way you are creating a "high current" ohm meter which over comes the standard VOM ohm meter by using brute force (15 Amps as opposed to a few milliamps).
