The IC was an LM2901 which is a comparator. 2 out of the 3 comparators used in the ECU were not working. The car is a '83 with motorola alternator, the battery is 3 months old. No zillas. The FV never worked since I had the car. The car had sat for 8 years in NJ. My friend said its possible if the IC was left in the cold and damp for a long time then had power applied to it, it could cause it to blow. Now i know what everyone means by being able to hear the FV!!
