To answer your wuestion: Yes you can tie it into the pos on the batt, but the sense wire will see a steady 13v from the battery and may not work as well as splicing the #2 wire into the feed just before it goes into the fuse block. No need to cut the feed wirem just strip back the insul about 1 inch, use a screwdriver to pry apart the strands, about 1/2 of the strands on each side of the blade, push the new wire thru the opening in the strands and wrap tightly, apply some solder and put on some liquid elec tape...... nice secure splice.

Pulleys for V-belt on CS series alternators are available. For example: 1 Groove V-Belt Alternator Pulleys. Stock V-belt pulleys can also be used, if the fan blades are directional they should match the rotation of the alternator.

I've done it using the stock pulley from the old alternator with no problems. Don't get me wrong, I like the CS130 for a few reasons. It's smaller and lighter than the SI family, has higher output, and has the separate field terminals that allow you to hook it up either with an idiot light or without - the external resistor is not needed. The two downsides are the cost of rebuild parts and the need to ensure a good ground to the rear frame. The second ex-wife had a stock CS130 in her Buick and the alternator would go bad every 12 months. After the third replacement I finally found the TSB that called out the need to add a ground strap from the rear frame to the block. Turns out that corrosion between the aluminum end frame and the steel stator core blocked the ground path for the regulator, causing it to fry. The strap fixed the problem (well, until she left, but that's a story for another forum...). Note that most cars that use the CS alternators have a bracket that bolts to the rear frame, acting as the ground path.
