Ford Ballast Resistor Wiring Diagram


What Does a Ballast Resistor Wire Do?

A ballast resistor wire is a device that is used to regulate the flow of electricity in a circuit. It is typically used in conjunction with an electrical relay or switch. The ballast resistor wire acts as a resistive element in the circuit, and its resistance determines the amount of current that flows through the circuit.

When the resistance of the ballast resistor wire is increased, the amount of current flowing through the circuit is decreased. This can be useful in situations where it is necessary to control the amount of current flowing through a particular circuit.

Where Does a Ballast Resistor Go?

A ballast resistor is a component in an electrical system that limits the amount of current flowing through it. It is usually placed in line with the positive lead of a circuit to prevent too much current from flowing and damaging the components. The resistance of a ballast resistor is measured in ohms and its value is usually chosen so that it will dissipate enough power to limit the current without being too large to cause significant voltage drop across itself.

How Do You Test an Ignition Ballast Resistor?

An ignition ballast resistor is a component in an automobile’s ignition system that limits the amount of current flowing to the ignition coil. It is usually a ceramic- or rheostat-type device, and is located between the coil and the switch on the positive side of the circuit. To test an ignition ballast resistor, you’ll need a multimeter set to ohms.

With the engine off, disconnect the wire going to the IGN terminal on the coil, and touch one lead of your multimeter to this terminal. Touch the other lead of your multimeter to a good ground point on the engine. If you get a reading of infinity (open circuit), then your ballast resistor is defective and needs to be replaced.

Do All Ignition Coils Need a Ballast Resistor?

No, not all ignition coils need a ballast resistor. In fact, many modern ignition coils don’t require one at all. However, if your vehicle’s ignition coil does require a ballast resistor, it’s typically located between the Ignition coil and the 12-volt power source.

The purpose of the ballast resistor is to prevent too much current from flowing through the Ignition coil. If too much current flows through the coil, it can overheat and fail.

How the Ballast Resistor Works

Ford Ignition Coil Ballast Resistor

The Ignition Coil Ballast Resistor is an important part of your Ford vehicle. It helps to regulate the voltage going to the ignition coil, which in turn helps to provide a consistent spark at the spark plugs. This ensures that your engine starts and runs smoothly.

If your ballast resistor fails, it can cause starting and stalling issues with your engine.

Symptoms of a Bad Ballast Resistor

A ballast resistor is an important electrical component in a vehicle. It is used to limit the current flowing through the ignition coil. If the ballast resistor is not working properly, it can cause a number of problems with the ignition system.

The most common symptom of a faulty ballast resistor is engine misfires. The ignition coil will not be able to generate enough spark if the current is limited by a faulty ballast resistor. This can cause the engine to run rough and may even cause it to stall.

Other symptoms of a failing ballast resistor include: -Dim headlights -Intermittent starting problems

-An engine that runs hot If you suspect that your car’s ballast resistor may be failing, it’s important to have it checked out by a professional mechanic as soon as possible. A failed ballast resistor can lead to serious engine damage if left untreated.

Running a Coil Without a Ballast Resistor

If you’ve ever wondered whether you can run a coil without a ballast resistor, the answer is yes! In fact, doing so can actually improve the performance of your ignition system. Without a ballast resistor, the coil will receive full voltage from the ignition switch.

This means that the spark will be stronger and more reliable. Additionally, it eliminates potential voltage drop that can occur when using a ballast resistor. Of course, there are some downsides to running without a ballast resistor.

One is that it puts additional strain on the ignition switch. Another is that if your coil fails, it could damage other electronic components in your vehicle’s electrical system. Ultimately, whether or not to run without a ballast resistor is up to you.

If you decide to do so, just be sure to keep an eye on your ignition switch and other electrical components to make sure they’re all holding up under the increased stress.

Ballast Resistor Voltage

When it comes to your car’s electrical system, the ballast resistor is an important component. It helps regulate the voltage going to your ignition coil, and ensures that your spark plugs fire correctly. Without a properly functioning ballast resistor, your car may experience starting problems, misfires, or a loss of power.

That’s why it’s important to make sure that yours is in good working condition. If you’re having trouble with your car starting or staying running, it could be due to a faulty ballast resistor. You should have it checked out by a mechanic as soon as possible to avoid further damage to your car’s electrical system.


If you’re having trouble wiring your Ford’s ballast resistor, this diagram should help. It shows how to wire the resistor in series with the ignition coil so that it can properly regulate voltage.
