Before replacing the alternator, consider the following: Take the old alternator with you when purchasing a replacement unit. Ensure the new or rebuilt alternator looks identical to the old one. Check the terminals on the alternator; they should match the old alternator in number, size, and location. Examine the identification numbers on the housing or tag, making sure they match between both alternators. Note that many new or remanufactured alternators may not have a pulley installed, so you may need to transfer the pulley from the old unit to the new one. Inquire about the shop's policy regarding pulley transfer.

Remove the upper and lower alternator mounting bolts and nuts. Unsnap the plastic insulator cap from the B+ output terminal, remove the nut securing the battery cable, and disconnect the cable from the B+ terminal. Disconnect the field wire electrical connector from the field terminal.
