measuring voltage when charging?
Is it best to measure voltage at the battery or at the converter / charger? How big of a voltage difference can there be between locations before I should look at upgrading the wire size? Linc

Save yourself the trouble and just replace the WFCO.
Otherwise for testing run your battery too low like 11.8 volts then have every possible 12v item running when you plug in. If voltage at the converter steadily rises above 14 volts you are doing better than most.
In addition to larger wire you may also need four or more batteries to get boost mode out of a 55a WFCO.
Technically you are looking for less than 13.2 volts at the converter during initial charging to trigger boost mode. Good luck.
