How do you convert a 1965 mustang generator to an alternator?

You don't convert a generator to an alternator. They are fundamentally different devices. A generator uses a commutator and brushes to produce DC current, while an alternator uses diodes to rectify AC current to DC. The internal workings are completely different and cannot be changed.

To get alternator functionality in a 1965 Mustang, you need to replace the generator with an alternator. This is a common upgrade and involves several steps:

1. Choosing an Alternator: You'll need an alternator that fits the 1965 Mustang's engine and mounting bracket. Many aftermarket alternators are specifically designed for classic Mustangs and come with mounting brackets and necessary hardware. Consider the amperage rating – a higher amperage will support more electrical accessories.

2. Purchasing a Conversion Kit (Recommended): These kits typically include the alternator, mounting bracket (if not already included with the alternator), wiring harness, pulley, and any necessary hardware. Using a kit simplifies the process significantly.

3. Wiring: The wiring is the most crucial aspect. The generator's wiring is incompatible with an alternator. The kit's harness will provide the correct connections, but you'll need to connect it to your existing wiring harness. This often involves connecting to the battery, ignition switch, and possibly a voltage regulator (though many modern alternators are internally regulated). Consult a wiring diagram specific to your Mustang year and model. A mistake here could lead to electrical problems or even damage to your vehicle.

4. Mounting: Securely mount the alternator using the provided bracket. Ensure proper alignment and tightness.

5. Pulley Alignment: The alternator pulley must align correctly with the engine's drive belt. Improper alignment can lead to belt slippage or damage.

6. Testing: After installation, test the alternator's output voltage to ensure it's charging the battery correctly. Use a voltmeter to measure the voltage at the battery terminals with the engine running. It should read around 13.5-14.5 volts.

Important Considerations:

* Voltage Regulator: Some kits include an external voltage regulator; others have internally regulated alternators. Make sure you understand your kit's components and wiring instructions.

* Belt Size: You may need a different size serpentine belt or V-belt to accommodate the new alternator pulley.

* Professional Installation: If you're not comfortable with automotive electrical work, it's highly recommended to have a professional mechanic perform this conversion. Incorrect wiring can cause significant damage to your vehicle's electrical system.

In short, you can't *convert* a generator; you must *replace* it with an alternator and use the appropriate kit or follow a detailed guide specific to your 1965 Mustang. There are plenty of resources online (including forums and YouTube videos) that offer step-by-step instructions and guidance for this common upgrade. Always consult a reliable wiring diagram for your specific Mustang model.
