The Ford 1G alternator is a high-output alternator that was used on a variety of Ford vehicles, including the Crown Victoria, Escort, and Mustang. This alternator was first introduced in 1985, and was used until 1995. The 1G alternator is easily identified by its large output wire that runs from the back of the Alternator to the positive terminal on the battery.
The output of the 1G Alternator is also higher than other alternators, making it ideal for use in high-performance applications.

What are the Three Wires on a Ford Alternator?
If you own a Ford vehicle, chances are you have an alternator under the hood. This part is responsible for generating electricity to power the engine and accessories while the vehicle is running. The alternator has three wires that connect to it – the positive battery cable, the negative battery cable, and the sense wire.
The positive battery cable is connected to the post on the back of the alternator that has a “+” sign next to it. This cable carries electricity from the battery to the alternator so it can be converted into AC power. The negative battery cable is connected to the post on the back of the alternator with a “-” sign next to it.
This cable returns unused electricity from the alternator back to the battery. The sense wire is attached to a terminal on front ofthe alternator. This wire tellsthe computer how much electrical load is being placed onthe system so it can regulate charging accordingly.
Without all three of these wires, your alternator wouldn’t be ableto do its job properly!
What are the Terminals on a Ford Alternator?
If your car has a Ford alternator, there are four terminals on it. The large output terminal is usually labeled “BATT” and is where the battery cable attaches. There will also be a small terminal labeled “IG” for the ignition switch, a larger terminal labeled “S” for the sense wire, and finally a ground terminal.
What is a Ford 1G Alternator?
A Ford 1G alternator is a type of automotive alternator that was popular in the 1980s and early 1990s. It is so named because it was used on the first generation of Ford cars equipped with electronic fuel injection. The 1G alternator is distinguishable from other types of automotive alternators by its large, bulky housing and its high output.
The 1G alternator was designed to provide high electrical current at low engine speeds, making it ideal for use with electronic fuel injection systems. However, its high output also made it susceptible to failure if not properly maintained. As a result, many 1G alternators were replaced with more reliable 2nd-generation (2G) units during the mid-1990s.
If you are driving a Ford car from the 1980s or early 1990s that is still equipped with a 1G alternator, it is important to have it checked regularly by a qualified mechanic. While 1G units are no longer manufactured, replacement parts are still available from aftermarket suppliers.
Does Ford Make a One Wire Alternator?
There are a few companies that make one wire alternators, but Ford is not one of them. One wire alternators are designed for cars that have a single wire going to the starter solenoid. The problem with using a one wire alternator on a car that wasn’t designed for it, is that the charging system will not be regulated and the battery will not charge properly.

Ford 1G to 2G Alternator Conversion
If you own a Ford vehicle from the 1G era, you may be considering an alternator conversion. The 1G alternator is notorious for failing, and can leave you stranded. Converting to a 2G alternator is a popular upgrade, as it is more reliable and will give your car better charging performance.
There are a few things to consider before embarking on this conversion. First, you will need to source a 2G alternator. These can be found at most salvage yards or online retailers specializing in Ford parts.
Second, you will need to modify the wiring harness to accommodate the new alternator. This is not a difficult task, but if you are not comfortable with electrical work, it is best to leave it to a professional.
Once the new alternator is installed, you will likely notice an improvement in charging performance and reliability.
If your car is prone to stalling or battery issues, this upgrade may be just what you need to keep your car on the road!
Conclusion
If you’re looking for a Ford 1G Alternator Wiring Diagram, you’ve come to the right place. Here at Mid-West Auto Electric, we have all the information you need to get your car up and running again.
The first thing you’ll need to do is find the positive and negative terminals on your alternator.
Once you’ve located them, it’s time to start wiring everything together. The positive terminal will need to be connected to the positive post on your battery, while the negative terminal will need to be connected to ground.
Next, run a wire from the alternator’s output stud to the ammeter.
Finally, connect the other end of the ammeter wire to one of the batteries’ terminals. And that’s it! Your alternator is now ready to provide power for your car.
