Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

hi everyone working on rebuild just had magdyno overhauld  new mcr2 fitted still not charging jim

eddie

Jim,
       If your dynamo has been sat around for some time since having it overhauled, it may have lost it's residual magnetism. To overcome this - assuming the bike is otherwise ready to run - remove the 2 wires from the back of the dynamo. You will see that the 2 terminals are labelled 'D' and 'F'. With a spare piece of wire, connect the 'F' terminal to the live side of the battery for a couple of seconds (be careful, the wire may get hot!). This will restore the magnetism in the field coils. Having done this, replace the 2 original wires and start the engine - the dynamo should now provide a charge with the correct polarity for your battery.

  Regards,
                Eddie.
