[QUOTE="highbury731, post: 123553, member: 1557"] No actual modification is needed to change the polarity of a dynamo. If a dynamo has not been used for a while, or if its polarity is unknown, then you need to flash it. Remove the D and F wires from the dynamo. Connect the battery earth as you wish, and take a lead from the battery feed terminal to the D terminal on your dynamo. Touch it repeatedly on the D terminal. It will give a spark. The dynamo is now of the correct polarity for your desired earthing. Paul [/QUOTE]
