[Healeys] Voltage Regulator Problems

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?
