Here is some additional info regarding installing alternators on the
2600 cars. I have just posted three photos showing the installation I
made on my 2600 1962 spider.

The bracketing can be made from 3/8" thick flat steel and two pieces
of pipe or tubing. The lengths of the pipe can be cut to provide the
offset required to align the alternator pulley with crank and water
pump pulleys.

At the time of the installation I converted to the newer style narrow
belt. The 2600 water pump was rebuilt adapting a 1750 or 2000 pulley
and making a new adapter to fit the 2600 fan. This conversion is not
not required. The standard belt can be used but the alternator will
have to be fitted with a pulley wide enough. The alternator pulleys
can be had in a variety of diameters which will affect the RPM when
the alternator will begin to charge.

There a two types of Delco GM alternators that can be used. Both have
built-in regulators. One is the newer "standard" alternater which is
called "self exciting". It has only one wire which is connected
directly to the battery. Pick up this connection from the existing
regulator which I left in place.

The second version is refered to as a 10SI type. It has an additional
wire that can be connected directly to the existing red "dynamo" dash
light. It will work the same as the regular generator, glow red until
the alternator voltage is higher than the battery, then it will go
out, indicating it is charging. This is the version I recommend. On
this installation the alternator has the normal Positive terminal plus
an electrical socket which requires a small "plug" with two wires. One
wire connects to the positive terminal on the alternator and the
second wire connects to the dash light. Be sure to buy the plug with
the alternator. I used the same set-up on my Model A when I converted
it to a 12 Volt system.

These alternators are available in 63, 78 and 94 amp version. All are
the same size and configuration. These are normal items for electrical
rebuilders.

I purchased my setup from a local rebuilder (SoCal Alternator and
Starter Exchange)here in the Los Angeles area. You can get more
specific info from them. Web Site is (www.socalaltandstart.com)
