I would guess the brushes in the alternator. I had my alternator in the
'92 go bad about 6 weeks back (nice having a large heap in the garage to
pull spare parts from). Took it in to a local rebuilder yesterday as I
noticed one slip ring was really worn badly. He called today - rotor was
shorted, all sorts of issues. Still only $122.50 for a full rebuild, and
its already done...
