Having just troubleshot my bad isolator I know that the sense wire from my alternator attaches to the starter wire on the isolator which then goes to the engine battery. I have never had an issue with the alternator not fully charging the batteries, nor would I expect that since the sense wire is on the other side of the diode.

Correct. By putting the alternator sense wire on the battery side of the isolator, the alternator puts out about .7 VDC more than the batteries see, with the loss occurring in the isolator. So, yes the batteries are properly charged at 14.
