Introduction
The Ford 3G alternator is an alternator model produced by Ford. It was introduced in the early 1990s and was used in various Ford vehicles, including trucks and vans. The 3G alternator represented a significant improvement in technology and quality compared to its predecessors.
Features and Specifications
The Ford 3G alternator is internally regulated and comes in different amperage outputs, including 150 and 225 amps, depending on the specific part number. It is available in a range of finishes, such as chrome plated, polished aluminum, stealth black, powder coated colors, and Factory Cast PLUS+ finishes. The alternator features a cast steel construction and is made in the U.S.A.. It also includes a pulley and is designed for use in Ford 5.0L models.
Benefits and Upgrades
Compared to its predecessors, the 3G alternator offers several advantages. It is more efficient and produces more amperage at idle. For example, a stock 3G alternator can put out over 100 amps at idle. The 3G alternator also uses two internal cooling fans, has sealed bearings, and features a superior battery stud. These improvements contribute to its reliability and performance.
The 3G alternator has become a popular choice for upgrading the charging system in older Ford vehicles. It provides a higher output and can handle additional electrical loads, such as off-road lights, stereo amps, and winches. The upgrade to a 3G alternator is particularly beneficial when the power requirements of the vehicle increase beyond what the original alternator can handle.
Installation and Compatibility
Installing a Ford 3G alternator may require some modifications or clearance adjustments, especially in older vehicles with different bracket designs. However, there are resources available, including wiring diagrams and pulley sizing guides, to assist with the installation process. Additionally, there are conversion kits and harnesses available that make the installation easier.
The 3G alternator is compatible with various Ford vehicles, including trucks, vans, and Mustangs. It is important to ensure that the alternator being used is the correct size and has the appropriate mounting style and pulley type for the specific vehicle.
Conclusion
The Ford 3G alternator is a high-output alternator model produced by Ford. It offers improved technology, higher amperage output, and enhanced reliability compared to its predecessors. The 3G alternator has become a popular choice for upgrading the charging system in older Ford vehicles, providing increased power for additional electrical loads. Installation may require some modifications, but there are resources and conversion kits available to assist with the process.

What are the three types of alternators?
Based on the current generation, alternators are as follows:
- Single Phase: It generates a single alternating voltage continuously for the vehicle.
- Two-Phase: It contains two windings to generate different amounts of current.
- Three Phase: it contains three windings and each winding is located at a difference of 120°.
Will a Chevy alternator work on a Ford?
Will a Chevy alternator fit a Ford? Alternators work about the same way on different makes and models, but each make and model has an alternator that fits correctly. It’s extremely unlikely a Ford alternator will ever bolt up on a Chevy, or that Chevy alternator will bolt up on a Ford.
How many amps is a 3G alternator?
The Ford 3G alternators utilize an internal voltage regulator and output 150 or 225-amps depending upon part number. They are available in a wide range of finishes including chrome plated, polished aluminum, stealth black, powder coated colors and Factory Cast PLUS+ finishes.
What is the difference between a 3G and 6G alternator?
The large case 6G puts out 90ish amps at idle. The large case 3G puts outs 75ish. The small case 6G puts out 70ish, the small case 3G puts out 60ish. If you’re comparing apples to apples, the 6g is the clear winner.
What is 3G alternator?
The 3G alternators are available stock in 95-, 130-, and 200-amp ratings. The fourth-generation design includes several different case configurations, including the “pancake” version used with 19962002 Ford Mustangs equipped with Modular V8 engines. Very compact, it came stock with 150- and 200-amp ratings.
Does it matter what alternator I use?
Factory electrical systems have differing tolerances, but if you’re planning on upping the requirements by more than 10 or 15 percent, then a high output alternator may be a good idea. If you just need a little extra juice, a car audio capacitor may be a better choice.
What is G in alternator?
A key to identifying your alternator terminals
| Terminal | Definition | Notes |
|---|---|---|
| G | Ground | Chassis negative connection |
| I | Inidcator | Warning Lamp |
| L | Lamp | Warning Lamp |
| M | Field | Found on older Externally Regulated units |
What is the difference between a Ford and GM alternator?
A GM alternator is typically around 2” and a Ford alternator is around 3”. The through hole between the two is different as well. Typically the GM is a 3/8” through hole and the Ford is a 7/16”. The other main difference is going to be in the center to center distance between the top and bottom hole.
What year is the 3G alternator?
1993-2004 (3G) The Ford 3G alternators utilize an internal voltage regulator and output 150 or 225-amps depending upon part number.
What is the difference between a 2G & 3G alternator?
<2> The new 3G large case alternator is rated at 130 amps compared to approximately 60-75 amps from the stock 2G unit. Additionally the 3G will produce more than double the output at idle speeds.
