[Mgs] [mgacars] RE: testing a generator from a 62 mga

Clayton,

Most likely a failure of the control box caused the generator to 
overcharge at too high voltage, resulting in melt down of the 
armature.  Melted soder in the commutator is "dead" giveaway of this 
problem.  Definitely check operation of the control box before 
putting the rebuilt generator back into service.  It is bad enough 
the a faulty $40 control box will take out a perfectly good $100 
generator.  It is really embarrasing if it happens the second time 
because the faulty control box was not replaced.
