ballast resistors

Green1, if you read the ORIGINAL post, the question was...How does a ballast reisitor work and effect the electronics. Only in subsequent posts does the OP even elude to his problem, then doesn't give any specific information about his car, the car's electronics or anything!! To lambaste 67Dart273 for explaining about ballast resistors??? Thats the ORIGINAL question. Until the OP gives some accurate information about his car and his problem, I don't mind reading about ballast resistors!! 67Dart273 is a very knowledgable source for Mopar electrical systems, I for one am listening and learning!!!
