An Electrical Nightmare
Any input on where to even begin would be greatly appreciated!
1...FIRST thing as suggested above is go to MyMopar and download the closest you can get to the correct factory service manual, and while you are there hit the "wiring" button and download the aftermark (2 pages) wiring diagrams, which are NOT factory, but are sometimes easier to follow
2...Determine why it is not charging. Find the "high voltage" connection on your ballast resistor. This should be the one jumpered to another end terminal. Read that voltage 'running' and find out what that voltage actually is
Below 13V not charging.......not good
About 14V running.......about normal charging
Above 15.5.........over charging, not good
Now determine why the alternator is not charging
Disconnect the GREEN field wire, and hook an alligator clip lead from that alternator terminal to ground with the key "in run." You should see a small spark every time you do that. With the clip lead in place and the key in "run" measure the blue wire at the alternator field. Do not disconnect it, probe with the connector in place. This should be VERY close to 'same as battery.'
Now start the car, with your meter hooked to battery, Slowly bring up RPM. Voltage should start to rise, adjust engine RPM to keep it below 16 or so.
If it does NOT and is below 13V the thing is not charging.
