Hyundai 37300-3E100 Generator Assembly

Before installing a new alternator, it is recommended to take the old alternator with you when purchasing a replacement unit. Make sure that the new/rebuilt unit is identical to the old alternator. Look at the terminals - they should be the same in number, size, and locations as the terminals on the old alternator. Also, check the identification markings on the housing or tag to ensure they match. If the replacement alternator does not have a pulley installed, you may need to switch the pulley from the old unit to the replacement unit. Inquire about the shop's policy regarding pulley swapping when buying a new or rebuilt alternator.
