[Mgs] testing a generator from a 62 mga

[PaulHunt73]

FWIW (now in the shop noted) the implication there is that the field winding 
is faulty.  This should measure 6 to 6.3 ohms as you say, but the book says 
the reading has to be 'much' below 6 ohms to suspect broken down insulation.

Did you test for continuity between the two brushes i.e. through the 
armature, while turning it slowly by hand?

When the commutator wears the insulators between the segments becomes flush 
with the segment surfaces, instead of recessed.    It sounds like that 
hadn't happened with yours.

I hope your $65 fixes it, regardless of the cause or the fix they apply!
