my buddy who is one of the smartest guys i know and has a mopar PHD had a duster that wouldent start and would blow fuses and burn up ignition boxes.i loaned him a full milk crate of old ignition control modules from my parts pile.he called the next day and said all of the boxes were bad!i told him i pulled alot of them from running cars so there was no way they were all bad.he had the battery hooked up backwards
