Parts Needed
* Alternator: You'll need an alternator specifically designed to fit a 1960 Cadillac 390 engine. Look for one with a compatible output (amps) and voltage (usually 12 volts).
* Alternator Mounting Bracket: The original generator bracket won't work with an alternator. You'll need a custom bracket or an adapter that mounts the alternator to the engine block.
* Wiring Harness: You'll need a new wiring harness specifically for the alternator. This will connect the alternator to the car's electrical system. You may be able to adapt your existing wiring, but this can be complex and is not recommended.
* Voltage Regulator: Some alternators include an internal voltage regulator, but many older models require an external one. Check if you need a new voltage regulator (usually mounted near the firewall).
* Battery Cables: You may need to replace or modify the battery cables to match the alternator's terminals.
* Pulley: The alternator needs a different pulley than the generator. This will align with the serpentine belt.
* Serpentine Belt: You'll need a new serpentine belt sized to work with the alternator pulley.
* Tools: You'll need standard tools for removing the generator, installing the alternator, and working on wiring.
Important Considerations
* Engine Modifications: The 1960 Cadillac 390 had a V8 engine with a front-mounted generator. Installing an alternator might require adjusting the engine's timing cover or using a different pulley system.
* Electrical System: The electrical system in your car may need adjustments for the alternator. This may involve changing the fuse box, relays, or wiring.
* Installation Complexity: Converting from a generator to an alternator can be a complex job, especially if you're not familiar with car electrical systems. It's best to have some experience with car repair or seek assistance from a qualified mechanic.
* Alternator Compatibility: When choosing an alternator, ensure it's compatible with the engine and its electrical system. You'll need to know the output requirements and voltage specifications.
* Resources: Consult a 1960 Cadillac repair manual or online resources specific to this model for detailed instructions and wiring diagrams.
Alternative Options:
* Generator Rebuild: Instead of replacing the generator with an alternator, consider getting the generator rebuilt. This is a more cost-effective option, but may not have the same benefits as an alternator (like higher output).
* Professional Installation: If you're not comfortable with electrical work, consider having the installation done by a professional mechanic. They can ensure that the alternator is installed correctly and that your electrical system is functioning properly.
Before You Start:
* Disconnect the Battery: Always disconnect the battery before working on any electrical components in your car.
* Safety Precautions: Work in a well-lit and ventilated area. Wear appropriate safety glasses and gloves.
Remember, converting a 1960 Cadillac from a generator to an alternator requires some electrical knowledge and mechanical skills. If you're unsure, seek assistance from a qualified mechanic.
