RWD:
Spot On!
Per your suggestion, I wired the ammeter stand alone to Batt + and Batt + voltage reg (shop manual schematic for "shunt type" ammeter and have repeatably secured the following:
1) An ammeter (and charging system) that appears to be fully functional or "normal".
2) A truck that shuts off when you turn the key off.
Both good reasons/ excuses to go for a ride.
Very Much Obliged!
