Tom, 

I am already planning on replacing the Generator in my 62 Classic with an
alternator.

I will use a GM Delcotron 10Si or 12Si.

A good wiring diagram for this conversion (Delco generator to Delcotron
with internal regulator, with a 3-wire connection so that the "idiot" light
on the dash will still work) can be found at this Corvair site (since the
Corvair used an indentical generator):

http://www.unm.edu/~geoffj/Vair/Alternator.html

Of course, I still have to either fix the 62 T96 by installing the
internals from the 67 T96, or to swap over the 67 Clutch housing...but
since I will plan on installing the 67 199, I guess I better keep the 62
housing so that the whole assembly can be installed in the correct
position, since the rear mounts are on the 62 housing. 

I think I will end up using the 67 insulators in the holes on the middle
(suspension) crossmember, and work up some adaptor plates to go between the
brackets on the sides of the 199 and the insulators. The difference in
mounting position looks to be about 2 1/2 inches forward from the 64-style
location, and about an inch to 1 1/4 inches higher.
I hope that plate stock will work for the plates. If the plates work out,
it could be a standard part for swapping in 7-main-bearing engines in place
of the 172-184-196.

I hope that the alternator swap diagram will be useful to others who are
looking to do the same swap as I will do.

Jim

We drove to a restaurant last night in the little American, because it 
warms up in one block (antique head design has it's advantages), about 8 
miles through typical LA stop and go surface traffic. When we went to 
drive off, whirrrrrrrr click. No battery! And we're in an inside parking 
lot with valet service (it's just an inexpensive Thai restaurant, but 
parking is precious) so we looked like loons pushstarting an antique car 
with peeling paint. Bumped it going easily.

(No -- valets refuse to drive it once they see three pedals and two 
sticks; I park it myself and STILL have to pay the $2!)

Put the little BATTERY MINDER on it and just now got back from 
diagnostics. Prognosis: SNAFU. Battery is fine (12.6V after 15 seconds 
of cranking). Gen puts out ~30 amps under test. Removed regulator, 
wirebrushed all the connections (they were corroded, but were not the 
problem). Passed all the TSM tests. Result: ITYS (I Told You So). 
Everyone said "generators suck in city traffic" and lo, it's true. Never 
had a problem before, but must have been s**t luck. But since it was 
(LA) "winter" fan was on high and the headlights were on, and it had sat 
for a week while I drove the Classic wagon. There you go.


PS: I found the car's serial number stamped on the cowl under the 
regulator. Matched the stamped stainless tag on the distributor side 
spring tower.
