no clue exactly what did it 1. ran a jumper cable between the neg terminal to a large ground outside that car and unhooked the + cable. 2. slowcharged the 3 month old "super premium" Interstate battery overnight with the cables off. 3. After reconnecting the battery I reset all my trip/service/oil counters. One week and the display hasn't started flashing after the car is off anymore. Which is good because next I was planning on taking every fuse and relay out and putting them back in.
