I have bought 3 open CDI’s and had a different error each time. Now I looked at my original CDI again and am a little confused now. It was called in the mains: battery disconnecting etc. or 61A, then AC. Now I see on the original (DC) and below stands 61A…what kind did I now????? The scooter starts on with disconnected battery???!!! 1.CDI smoked. 2. CDI fuse flown. 3. CDI black cable pinned out and there for the black/white pinned. 5x start attempt, after which the fuse flew
