Cleanup turns to mess up. Need some help troubleshooting.

You provided a good data point for this issue: 9.4 volts to the 2 blue wires on the ballast, with the ignition switch in RUN (not cranking), is too low; it should be no more than 1/2 volt below the battery voltage. Get out the wiring diagram and start to trace from that point back to the ignition switch with the switch in RUN, and then back to the battery; you have excessive voltage drop somewhere. That needs to be fixed as you have a bad connection or wire or ignition switch.

BTW, in your last pix, the ballast has a crack in it. Replace it as it could be causing the 'off like a light switch' symptoms; that's not obsessing! LOL

I broke out my meter last night and tested all the wires except for the ignition switch in terms of resistance and everything tested out fine. The two wire connector to the distributor for the ECU that is supposed to be between 150 and 900 ohms came in at 279 ohms. So that tested out good.

With the battery at 12.0 volts the two leads on the ballast resistor tested at 10.1 volts with the ignition in the "on" position. SO I have to figure out why I'm dropping 2 volts when I have a spare ballast resistor in the trunk that I can throw in the car to get rid of that cracked one so no worries there. What is the easiest way to get to the ignition switch for testing?
