[TR] TR4 Generator Electrical Arcing

[glemon at neb.rr.com (Greg Lemon)]

Paul, here is a quite detailed article on servicing a Lucas dynamo.

More theory than I would ever want to know or understand, but go to page 17 
for maintanance.

Lastly I believe the factory and Haynes manuals usually have instructions on 
cutting down the Micanite insulation between the commutators, but I couldn't 
find a reference on the internet, but the article above does refer to 
sparking and polishing the commutator.
