I have a set of Dakota under-dash gauges - temp, oil pressure, and ammeter. That's where I'm getting my 14a reading. The voltage regulator on the firewall was eliminated because this alternator has an internal regulator.
So unless someone screams "FOUL" I'll run a 10 GA wire to the batt. terminal on the starter and take readings at the battery. And then yes, make work of tracking down where the other end of that harness wire is. (I suspect I ran it to the dash, but hopefully not)
