High Charging Rate. Found Voltage Drop Need Guidance Please

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.

I didn't get near the car today (house priorities). Hopefully tomorrow. Nice professional crimp shown in the pics you sent. What kind of crimper do you use? I have a good Klein T1715 that handles closed insulated terminals and butt joins but not sure that it will do the job on the Chrysler open barrel terminals.
