See Figures 1, 2 and 3
All models covered in this repair guide use a 12 volt alternator. Amperage ratings vary according to the year and model. All 1970-79 models utilize a separate, adjustable regulator, while 1980 and later models come equipped with either a separate, adjustable regulator or a transistorized, non-adjustable IC regulator, integral with the alternator.
To prevent damage to the alternator and regulator, the following precautionary measures must be taken when working with the electrical system.
REMOVAL & INSTALLATION
See Figures 4, 5, 6 and 7
On some models the alternator is mounted very low on the engine. On these models it may be necessary to remove the gravel/splash shield and work from underneath the car in order to gain access to the alternator
- Disconnect the negative battery cable.
- Unfasten the starter-to-battery cable at the battery end.
- If necessary, remove the air cleaner to gain access to the alternator.
- Unfasten the bolts which attach the adjusting link to the alternator. Remove the alternator drive belt.
On some late model vehicles on which the alternator belt also drives the power steering pump, it may be easier to loosen the power steering pump and pivot it inward to release tension from the belt, then remove the belt from the alternator pulley
- Unfasten the alternator wiring connections.
Diesel engine alternators are equipped with a vacuum pump. Before removal, two oil lines and a vacuum hose must first be disconnected
- Remove the alternator attaching bolt(s) then withdraw the alternator from its bracket.
- Installation is performed in the reverse order of removal. After installing the alternator, adjust the belt tension as detailed in General Information & Maintenance of this repair guide.
