I got to play with the 7 for a few minutes yesterday trying to diagnose the issue with no power going to anything. Biggest issue I found was loose battery connections and old soft cable ends. As soon as I got the cable ends fixed I had power and got her to fire off. The issue now is that the switch seems to have an issue. As soon as you let the key turn back to the run position it apparently looses power and the jeep turns off. Bad ignition switch?
Have you replaced the ballast resistor you originally found broken?
Remember this post?
The block in the picture looks like the old style ballast resistor that was used to limit the voltage to the coil after the engine starts and the ignition switch is in the "run" position. The coil would typically get full battery voltage when cranking.
If it is, test the output from the resistor.
Is the new replacement resistor the same ohm resistance as the old one?
As you have found out connections are important with the low voltage (12 volt) used in automotive wiring.
Keep at it simple tests will find the problem.
