My thinking is thus: if the ECM is broken and the ECM controls the alternator;
The computers are supposed to be able to operate on 10V, there are a lot of reasons that less than 10V gets to them even with a full battery.
The output of the alternator varies, it is not a constant 14.4V.
A slightly low battery usually manifests more as a failure of a sensor on the 5 V ref first, not the ECM.
QED : it is not the battery being slightly low but the ECM.
Yes, this is donbrew blaming the computer.

Salvage yard parts Center asked for the part number of my PCM to match it to
This salvage yard has a parts store attached to it, stocked with salvaged parts. So I called them up cuz they got some for between 35 and 50 dollars online. The fella asked for the part number off mine. So I went to try to find it, and I don't know what I should and shouldn't touch or take out. How do you pull the PCM out and look at the number??

Closure to the battery question? 2nd test results
This is a picture of the receipt.
Not sure if this helps bring any closure to the battery question. But I wanted to rule that out as a possible issue.
