This manual provides essential instructions for the installation, operation, and maintenance of your Powermaster 48516 200 Amp Ford 6G Alternator. Please read this manual thoroughly before installation and use to ensure proper function and safety.
The Powermaster 48516 is a high-output 200 Amp alternator designed for Ford 6G applications, featuring a 6-groove clutch pulley and a large frame. It is PCM controlled with LI-SIG-A VR regulation.
2. Safety Information
WARNING: Always disconnect the vehicle's battery before working on any electrical system components to prevent electrical shock or damage to the vehicle and alternator.
- Ensure the vehicle's ignition is off and the battery is disconnected before installation or maintenance.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Avoid contact with moving parts when the engine is running.
- Improper installation can lead to vehicle damage, fire, or serious injury. If you are unsure about any step, consult a qualified automotive technician.
- Do not operate the alternator without proper belt tension.
- This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. (Proposition 65 Warning)
3. Package Contents
Verify that all components are present before beginning installation:
- Powermaster 48516 Alternator (6G 200A 6 grv Clutch Pulley)
- Instruction Manual (this document)
- Additional mounting hardware or accessories may be included depending on the specific application kit.
4. Setup and Installation
The following steps outline a general installation procedure. Specific vehicle models may require variations. Refer to your vehicle's service manual for detailed instructions.
- Preparation:
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the negative (-) battery terminal first, then the positive (+) terminal.
- Locate the existing alternator.
- Removal of Old Alternator:
- Loosen the belt tensioner and remove the serpentine belt from the alternator pulley.
- Disconnect all electrical connections from the old alternator (main battery cable, regulator wires). Note their positions for reinstallation.
- Remove the mounting bolts securing the old alternator to the engine bracket.
- Carefully remove the old alternator from the vehicle.
- Installation of New Alternator:
- Position the Powermaster 48516 alternator into the mounting bracket.
- Install the mounting bolts and tighten them to the vehicle manufacturer's specifications. Do not overtighten.
- Reconnect all electrical connections. Ensure the main battery cable is securely fastened to the alternator's output stud. The 6G alternator typically uses a 3-wire connector for the regulator (LI-SIG-A).
- Reinstall the serpentine belt onto the alternator pulley and adjust the tension according to vehicle specifications.
- Final Steps:
- Reconnect the positive (+) battery terminal, then the negative (-) terminal.
- Start the engine and check for proper charging voltage (typically 13.8-14.8 volts).
- Listen for any unusual noises from the belt or alternator.

5. Operating Instructions
The Powermaster 48516 alternator is designed to operate automatically once installed correctly. It is controlled by the vehicle's Powertrain Control Module (PCM) which regulates its output based on the vehicle's electrical demands and battery state.
- Upon starting the engine, the alternator should begin charging the battery and supplying power to the vehicle's electrical system.
- Monitor your vehicle's voltage gauge or dashboard warning lights. A healthy charging system typically shows voltage between 13.8V and 14.8V.
- If the battery warning light illuminates, it indicates a potential issue with the charging system.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your alternator.
- Belt Inspection: Regularly check the serpentine belt for cracks, fraying, or excessive wear. Ensure proper belt tension. A loose belt can cause slippage and reduced alternator output.
- Electrical Connections: Periodically inspect all electrical connections to the alternator for corrosion or looseness. Clean any corrosion with a wire brush and battery terminal cleaner.
- Cleanliness: Keep the alternator free from excessive dirt, oil, and debris. A clean alternator dissipates heat more efficiently.
- Battery Health: Ensure your vehicle's battery is in good condition. A weak or failing battery can put undue strain on the alternator.
7. Troubleshooting
If you experience issues with your charging system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery warning light on | Loose or worn serpentine belt, faulty electrical connection, internal alternator failure, dead battery. | Check belt tension and condition. Inspect and clean electrical connections. Test battery. If issues persist, have the alternator tested by a professional. |
| Low voltage reading (below 13.5V) | Excessive electrical load, loose belt, faulty wiring, internal alternator issue. | Reduce electrical load. Check belt. Inspect wiring. Test alternator. |
| High voltage reading (above 15V) | Faulty voltage regulator (internal to alternator or external PCM issue). | This can damage electrical components. Have the charging system diagnosed immediately by a professional. |
| Squealing noise from engine bay | Loose or worn serpentine belt, misaligned pulley. | Inspect and adjust belt tension. Check pulley alignment. Replace worn belt. |
