Car wont start unless door is open
With voltage, you can check to see if connections are being made.
This is the feed for ignition running (I called it J2, but the shop manual for '73 shows it as J2C, go figure, the draftsman didn't have his coffee that morning)
There should be power there with key in run.
There should also be power on the J2A where it connects to the ballast resistor, and at the blue connection on the alternator.
There should be a junction on the connector at the ballast, that leads to the ECU power wires when running.
Use resistance when trying to determine if two ends are connected. There must be no power in the wire being checked.
