Yes, done that. The truck was 12.6V resting and 14.3 running. The trailer was 12.6V not connected to the truck.
And only reported half the results.

So....what did the trailer battery read when connected to the running truck? And what did the truck battery read at the same time.....or a few seconds later ??
And a P.S. after reading another post of yours:
Measuring the voltage on the battery cables while they ARE NOT CONNECTED TO THE BATTERY proves pretty much nothing.
And now I have forgotten what the original question was.
o....what did the trailer battery read when connected to the running truck? --14.3V

Measuring the voltage on the battery cables while they ARE NOT CONNECTED TO THE BATTERY proves pretty much nothing.--My thought was to measure the charging voltage coming from the truck to the trailer batteries independent of the batteries. Analogous to measuring the output of he convertor.
Anyway I now think the problem is with the trailer and will test it when I get home and have more tools and time.
