Thanks for the data. The 12v in and out of the ignition switch is good the 10.9 vo at the ballas tin put is a bit on the low side; the issues dropping this are likely the connectors at the firewall or out of the switch. A good cleaning if the contacts is in order.
The 3 module pix are: #2 is the charging systems voltage regulator. #1 and #3: I don't know! I don't have those on any diagrams. Can you give us the PN off of those, or any info as to where the non-blue wires from their connectors go? Those certainly are odd and I have to wonder how much current they are pulling and no helping the voltage to the ignition. But the car ran before right?
Test the ballast with your ohmmeter to see which side is the 0.6 ohm side and make sure that is the side that the coil current passes through. You'l also have a test of the resistance values to make sure it is right. Your harness looks to have the orientation tabs intact on the ballast connectors so it is probably OK, but just check anyway to be sure.
Once the hacks are fixed as well as you can (and I wish I had some good suggestions there), you're at the point to start running some tests for spark as suggested. Get some more data points.
