I have enjoyed the first 7 months of R4466 but I have one slight annoyance.
The charging system does not keep up when the air conditioning blower is in
use.  I believe it is a weak alternator.  The max charge she'll show on the
ammeter is about 20 amps.  The car does fine when the air is'nt on but when
it is it does not have enough reserve to start after a 20 mile trip.  Since
my other Stude is a 6 volt, I thought I'd ask the group before I tear into
it this winter.

The alternator is a Prestolite ALE 5002 BL and it is larger than an
original, but similar in appearance.  I think it's a GM application.  I
haven't bench tested it yet.  The case was modified to fit because the top
bolt hole rubbed the hood.  Any suggestions if it's the culprit?  The car is
used for pleasure and it is not a 400 point winner.  I'd like to keep the
look as original as possible.  It's an R1 4-speed with factory air.

You may want to get the correct prestolite alternator for your Avanti 
The Prestolite ALE 5003 alternator was used on both R1 & R2 engines (40
amps). The Studebaker part # is 1556902. 
The case mounting ears tend to get broken, soo look carefully when buying
one and make sure upper and lower bolts are loose when you tighten them.
Many people loosen one and break the other while tightening or during
operation. They can be rebuilt (for about $90) if you find a good doner. 
You may want to go to a buisiness that repair fork lifts (many of them use
the same presolites!). If you find one without the right decent metal tag on
it, you can also buy a new prestolite tag from Studebaker of CA. 
You can also fit other high amp units into your car. 
You can use a Wilson #90-29-5034 or NAPA #A8759.
They will bolt right in, but you need to rewire to get rid of the Prestolite
regulator as the new alternator has a built-in unit. It is not a single wire
unit either. They are a good fit in the valley and are 60amp units, much
higher than the standard 40amp original unit Studebaker used. Give NAPA a
call and then check if it is the same as a 1981 Toyota Tercel.

While working on the wiring of my 64 R-2 I noticed that tthere is a
black and a white wire in the rear harness that leads to each of the
rear dome lights.  The way these are then connected to the socket in
the housing is such that the white wire is grounded to the housing.
The manual calls for a 1004 bulb, but such a bulb will ionly light if
both the hot lead and the ground are aapplied to the twin contacts,
i.e. the base of the bulb is not grounded to the filament.  So the way
it is wired I don't see how a 1004 bulb can work.  Does anyone know
how the dome light arrangement is supposed to work?  Thanks for any


---------------------------------
  Are you sure one of the base contacts is not grounded inside the
housing ?

I had the same problem with my 51  the only way to make it work is to run a
ground from one side   it should show one in the wiring diagram if you look
really close
