John,
You are right. I am getting older and it was some time ago I did it. There are
only two brushes in the generator. I did as you described and ended up with
putting 24 volts on the indicator lamp.

I believe that you might be slightly wrong with the detail but it has led me
to an idea. There are only two brushes and I cannot see how these could be
fitted in any other way. However I can see that if the field coil is replaced
it would be fairly easy to solder the two leads to the 'F' post and the large
tag to the body of the generator the wrong way around. As Rich says he has
tried polarising many times and most likely the residual magnetism is now
established BUT the wrong way round.
Therefore the output at the 'D' terminal will be in the opposite polarity.
Thus producing 12 Volt in opposite polarity to the battery and putting 24 volt
on the indicator lamp and burning it out.
Rich - I this possible?

just move the brushes to brush holders 900 back or forth.
