I work in the automotive sector, with experience of refurbishing alternators and starter motors. It always puzzled me when told the electron flow from neg to pos - why? Because logically AC current is produced by the alternator, sent to the rectifier and then bumped up to very high voltages at the HT coils and then discharged through the spark plug. Surely the electron flow implies current flows the other way? The same principle would apply for the starter circuit too. Even allowing for Hole theory (?) it's all a bit bizarre really. As humans have we somehow missed a fundamental law in our perception of how current really flows I wonder? Do we truly understand electron flow and is hole theory proven scientifically?
