Dodge Repair: Voltage trouble 93 Dynasty, wireing harness, voltage problems

Question
Having problems with my 93 Dynasty 3.3L with a A604 Auto trans. Recently replaced Battery, Alt. and Output speed sensor and connector with no change. Over the past year voltage meter has been showing a drop When I come to a stop and is geating worse to the point where car will stall occasionally. Speedo works once and awhile, with no change after new sensor. I live in canada and the colder it gets the better the car runs.As the engine warms the voltage problems happen. Rad fans, lights and blower motor all cause voltage drops and will not recover after engine is warm. Any idea's?

Answer
Hello Randy
you have to change the alt wires in the wireing harness this wire is bad and geting ready to break this is why the voltage drop you are geting .

i just had a 1992 dodge truck with the same problem that would not start at all. changed the starter wires threw harness fine now pete
