These days alternators are getting more and more costly (up to several hundred dollars depending on the application) while intermediate rebuild kits are very inexpensive and once you've done it, very simple to do. | These days alternators are getting more and more costly (up to several hundred dollars depending on the application) while intermediate rebuild kits are very inexpensive and once you've done it, very simple to do. | ||

| + | Here’s three different GM alternators, on the left is the '''10DN''' which uses an external regulator. In the center is the internally regulated 10SI (Systems Integrated) used from the later ’70s. The serrated end that makes it easy to spot. On the right is the CS130. | ||

| + | The connector is usually labeled PLFS or PLIS. The only wire used is the '''L''' position, it's connected to the dash light. Do not connect this to a 12 V source, as that will damage it. If a dash light isn't used, install a 50 to 80 ohm, 5 watt resistor in series to a ''switched'' power source. On connectors without any markings as to which wire/terminal is which, use the ''third position counted from the large end of the connector'' for the dash light or resistor. | ||

*With a fine emery or crocus cloth, burnish the brush pickups or (slip rings) on the rotor assembly until smooth and shiny. Emery dust is conductive so clean up your work when done. | *With a fine emery or crocus cloth, burnish the brush pickups or (slip rings) on the rotor assembly until smooth and shiny.

* Install your new bearing, but before you do, get a SMALL sharp punch and carefully put a dimple in the race each 1/3 rd the way around. One may use a dab (small dab) of epoxy to accomplish locking the bearing race. This will prevent the race from spinning in the case. It will be a tiny bit harder to put the cases back together, you might have to tap the halves with a rubber mallet. | * Install your new bearing, but before you do, get a SMALL sharp punch and carefully put a dimple in the race each 1/3 rd the way around.
