[Vwdiesel] Rebuilding 90w Alternator

[Val Christian]

I simply solder on new brushes.  It's about 30 minutes of work, and then 
one is good for a year or two.  Worn brushes is a cause of incomplete charging,
and that could be a hassle with ovalized mounting holes.  The last time I
bought brushes, I got 20 for $10.  Getting them in pairs from the franchise
parts store, they run $4 to $6 a pair.
