High Charging Rate. Found Voltage Drop Need Guidance Please

@Mattax

Interesting thanks. Excuse my ignorance but do the plastic covers open up for removal/reinstall? I'll definitely be checking out the ballast ignition terminal. I'm suspicious about the wire added for the ECU. Are the Chrysler style terminals readily available?
Depressing the barb on the back of the terminal releases them.
Yes Chrysler terminals are available. If you have original harness and conectors, thats what you want.
If you have a repop harness, it may have packard 56 terminals and connectors. If so, that's what you'll need.
