Key Features:
– The 6G alternators have an internal voltage regulator and utilize the OEM wiring plug.
– They are available in various amp ratings, including 135, 150, and 225 amps.
– The alternators include a 6-groove pulley or clutch pulley, depending upon the part number.
– They are available in different finishes such as chrome plated, polished aluminum, stealth black, and Factory Cast PLUS+ finishes.
Identification and Types:
– The 6G family has two main types with different amp ratings: a lower amp at 110 Amps and a larger frame at 135 amps.
– There are four different types of regulators for the 6G alternator, identified by the product number system with letters representing different regulator types.
– The 6G family also has variations in the rectifier.
Applications and Upgrades:
– The 6G alternator is used in various Ford vehicles and is a popular replacement for increased charging capacity at all RPM ranges.
– It is known for its high output power and is used in SUVs, trucks, vans, ambulances, and limos to increase available power.

What is a 2G alternator?
The 2G alternators for Ford have an internal voltage regulator and utilize the OEM wiring plug. Available in chrome plated, polished aluminum, stealth black and Factory Cast PLUS+ finishes. These alternators are built with a 75 or 100-amp ratings and include a 6-groove pulley.
What is the difference between a type and B type alternator?
There are two types of alternator charging systems: Type A (sometimes called grounded regulator) and Type B (grounded field), which is the most common. Type B systems control field current before the alternator; Type A systems control the field current after the alternator.
What is the difference between 2G and 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.
How do I identify my Motorcraft alternator?
The Motorcraft 1G alternator can be easily identified by the four wiring connectors on the back of the unit. Plastic color-coded rings (red, orange or white and black) usually surround three of these terminals.
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 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 a Ford 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.
How can I tell which alternator I have?
– Observe the general appearance of the alternator, check the number of mounting points and their arrangement. – Count the number of grooves on your pulley. – Check the amperage rating of your alternator. – Check the alternator’s connections, its connection pin.
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.
Does it matter which alternator I buy?
While all alternators have a voltage regulator, some are internal while others are external. Choosing the wrong one won’t work with your vehicle in most cases. Size. Of course, physical dimensions make a huge difference in whether an alternator will fit in place of your old one.
