Every last one of you were correct. I moved the alternator grounds to the negative busbar AFTER the shunts. Monitors now show current from the alternators to the batterries. THANKS!

Do you also now see 14+V when charging / alt running?

I discharged overnight while at the dock down to 55%. Started engines. Alternators charged at 100 amps (combined) at 1,000 engine RPM. Voltage at 12.9. Batteries began taking a charge immediately. Turned off engines and went to shore power. Charger putting out 125 amps, 13 volts. Since both charge sources are charging at virtually the same voltage, I believe all is well. Alternator output voltage should ramp up over time during the bulk charging period but I won't know for certain until we go out for an extended cruise.

Yesterday morning my house battery was at 12.1 before engines started for a 3 hour trip. The graph shows alternator charging at 13.3-13.4 during this time. Amp started 60, dropped to 30 (this not graphed, just observed).
On shore power the inverter charger was 13.7-14.2 (fridge/freezer load on).
The charger is 3 stage before it goes to float at 13.5 which is what it is doing this morning.
