While pulling away from a light at about 4000 rpm, my alternator light and O2
light came on.

First I thought I threw the belt, but that wasn't it.  Belt is in place,
alternator is turning, no output.

I pulled the alternator, and removed the regulator to check the brushes, and
they were in firm contact with the slip rings.  Put it all back in and
restarted the engine in the vain hope that dis/reassembly fixed things.  No go.

Checked with NAPA, and a rebuilt from them is 224 to 250.  Ouch!  Checked at my
FLAPS, and they have one for 88 with a lifetime warranty.  The difference is
that the original has a B+ only, while the replacement has B+ and D+.  I'm
guessing the D+ is the feed to the voltage regulator, and that it can be
jumpered to the B+ for local voltage sense, or I can run a wire to the battery
for remote voltage sense.  Am I correct in what I think D+ is for?

If so, I'll pick this one up tomorrow.

TIA
