Alternator wiring issues
GET AND READ a shop manual The guys at MyMopar spent a lot of time and likely money posting archives of service manuals. Some of them over there came from some of us right here. So go to MyMopar and download a service manual for your car. You may have to settle for Plymouth vs Dodge or vise versa.
Also there are aftermarket wiring diagrams, w hich are somewhat easier to read, sometimes, BUT WHICH sometimes leave out details and connectors.
