My bike has been off the road for the last month or so whilst the Lucas ‘N1’ magneto and ‘E3NL’ dynamo were back in the UK being reconditioned.
The magneto had started to fail intermittently a few weeks before and then lost it’s spark completely, and the output from the dynamo seemed to be flickering at around the same time. So it seemed sensible to get them both overhauled at the same time.
I’ve recently got the dynamo back and it looks great, almost better than new! The body has been polished up and the metal strap around the end painted shiny black. It also has a new end cap (the old one had a big hole in the end right over the bearing), but of course most importantly of all it has a new armature inside which will hopefully provide a more reliable voltage output.
It also now has a few extra parts that it was missing before, the main one being the metal strip which screws onto the side of the dynamo body and which helps to align it between the engine plates. I suspect that this will take some trial and error to get set-up in the right position to start with, but it will mean that if the dynamo ever needs to come out again in the future, it can then just slot back in to its correct position again afterwards.
So here are a few photos of the dynamo taken before and after it was sent for reconditioning so you can see just how different it now looks. Clicking on any of the pictures below will open them up full size for a better view.
