What is a Ford 2G alternator?

A Ford 2G alternator is an alternator model that was used by Ford in their vehicles during the 1980s and early 1990s. It was introduced in 1982 as an upgrade to the previous 1G alternator. The 2G alternator is internally regulated and has a specific wiring harness. It was commonly used in Mustangs from 1986 to 1993.
The 2G alternator had some reliability issues and was known for its external cooling fan. It was eventually replaced by the 3G alternator in 1994, which addressed the shortcomings of the 2G model. The 3G alternator featured internal cooling fans and improved reliability.
The 2G alternator had different amperage ratings and pulley sizing options, depending on the specific vehicle and application. It was commonly used in small- and big-block Fords and had a single-groove pulley with a diameter of 2.62 inches.
Overall, the 2G alternator was not as reliable as its successor, the 3G alternator, and had some known faults, such as undersized positive charge wires and plug failures. Many Ford owners have chosen to upgrade from the 2G to the 3G alternator for improved performance and reliability.

Why 2G is better than 3G?

However, when 3G mobile networks were deployed, they did not immediately offer the same coverage as 2G. This is because 3G technologies operate at a higher frequency than 2G and as such the coverage extended by a 2G tower can be upto 10km whilst a 3G tower can only extend up to 3km.

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.

Why 2G is better?

Advantages of 2G Technology
The first advantage of 2G technology was that it provided better sound quality than 1G technology. 2G technology had increased capacity, which meant that it could handle more users at a time. 2G technology allowed for the development of text messaging and multimedia messaging.

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°.

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.

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.

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.

What is a Ford 6G alternator?

The 6G alternators have an internal voltage regulator and utilize the OEM wiring plug. These alternators are built with a 135, 150 or 225-amp ratings and include a 6-groove pulley or clutch pulley, depending upon part number. Available in chrome plated, polished aluminum, stealth black and Factory Cast PLUS+ finishes.

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.
