Take out the lug nut connected to the negative terminal of the battery and detach the cable from it. undefined Note: In these models, access is usually very limited. Since it will be necessary to get to it, some of the elements will have to be disassembled. These components are not standardized across models. Remove electrical connectors from the alternator. Bolt is located on the top of the alternator, and the solution is to unscrew it and take out the alternator. When buying an alternator, it is important to take the old alternator with you in case you are replacing it. Ensure that the new or rebuilt unit has the same specifications as the old one, specifically the alternator. Check the terminals-the number of terminals, their size and the places where they should be immobilized should correspond to the number, size and places of the terminals of the old alternator. Finally, consider the identification markings-these will be either stamped into the housing itself, or else they will be printed on a tag or plaque that has been fixed to the housing. Ensure that these numbers are the same for both alternators. If the replacement alternator does not come with a pulley installed then you may need to transfer the pulley from the damaged unit to the replacement unit. In case of purchasing a new or rebuilt alternator, one should enquire about the pulley swapping policy of the shop. In some shops, they will do this as a complimentary service. Removal is the opposite of installation. After the alternator has been fitted, read the voltage output to ensure that the alternator is functional.
