Ok here is another one! got a 72 challenger, with the car running and the turn signals on in either direction the tach jumps with each bulb flash. so if its idle is at 1k each bulb flash the tach jumps down to 500 ... also if the radio is on each time the turn signal is initially activated it will make a pop from the speakers. Not with each bulb flash like the tach but only on the first activation of the signal....So far i've added seperate grounds to the instrument cluster housing, radio, flasher, back of tach and nothing has made a change .. The gorund is the only thing i can see in common ... any ideas ?
