I’ve got a 468 Shelby aluminum block in my Cobra that was rebuilt by Keith Craft in 2009, this is CSX4188. The engine and car run great. Last weekend I turned on the ignition and smoke billowed out from the ignition box under the dash. I cut power and removed the box, it smells of burnt wire and is definitely fried. All other items seem to work well with the box out, fuel pumps, fan, lights and starter all perform well. The box is a MSD Digital-7 programmable #7530. I’ve ordered a new one, #7530T that appears to be a direct replacement. Can you offer any advice on what if anything I should do when I install the new ignition box? Will this need to be programmed before installation?
