voltage regulator

[PeterBergin at aol.com]

First time it just went out,no charging.  Brushes were barely  good.  The 
second time brushes were worn, but the alternator shaft had  about an 1/8 
grove worn on it from the brushes.  I had a few days were it  would work 
intermittently before it went dead.  I bought a bosh  remanufactured.  On my old 
5000 Avant, the regulator failed and I lost  about 1/3 of the full output.  I 
think it may have been a diode, but that  was 15 years ago.
 
Good luck.  Pete  
 
PS ,channel  11 on the AC head displays volts,  usually about 1  volt less 
than I measure on the battery.

Thanks  Pete,

what were your symptoms of a worn out regulator?

my car  has 119k (but regularly acts like it has 319k  ;-)

My first regulator failed  at 150k, the alternator shaft was worn out at  
200k.
