70 up charging system upgrade question

So I redid some more tests
12.45 Battery v static
11.22 battery direct cranking.
With ecu and ballast resistor unhooked.
1. Ign2 terminal at ballast and batt -ve 1.3 mV, key OFF, key START 11.10 V, key RUN 0.6mV
2. IGN1 terminal at ballast resistor and batt -ve 2.3mV key OFF, key START 56mV, key RUN 11.77 V.

The start voltage seems good(11.10v) as compared to battery cranking (11.20v).
Could new ECU bu bad? I have another new one but dont wanna keep throwing parts at it.
Could I have messed up the wiring when I "upgraded" to 70 + VR and alt?
Thanks!
