1986 Mustang Starter Solenoid Wiring Diagram

If you are a proud owner of a 1986 Mustang, then you know how important it is to have a properly functioning starter solenoid. The starter solenoid is responsible for powering your car’s starter motor, allowing you to start your car with ease. However, if your starter solenoid is not wired correctly, you may experience various issues such as your car not starting or even damage to your electrical system. In this article, we will provide you with a comprehensive guide and wiring diagram for your 1986 Mustang starter solenoid to ensure your car runs smoothly.

What is the Starter Solenoid?

The starter solenoid is a crucial part of your car’s starting system. It is responsible for engaging and disengaging the starter motor from the engine flywheel. The starter motor is what turns the engine over, allowing your car to start. The solenoid functions as an electrical switch that receives power from your car’s battery and sends it to the starter motor. When you turn the key to start your car, the solenoid receives a signal from the ignition switch, which in turn completes the circuit, allowing the starter motor to engage and start your car.

How does a Starter Solenoid Work?

The solenoid contains two large copper contacts that are connected to the battery and the starter motor. When the ignition switch sends power to the solenoid, an electromagnetic field is created, which causes a plunger to move within the solenoid. The plunger connects the two copper contacts, completing the circuit and allowing electrical current to flow from the battery to the starter motor. Once the engine starts, the ignition switch disengages the solenoid, disconnecting the copper contacts and turning off the electrical current to the starter motor.

Common Symptoms of a Failing Starter Solenoid

If your starter solenoid is failing or not wired correctly, you may experience various symptoms such as:

Symptoms of a Failing Starter Solenoid Description
Car not starting If you turn the key and nothing happens, this could indicate a bad starter solenoid.
Clicking noises If you hear a clicking noise when you turn the key, this could indicate a failing solenoid or low battery.
Smoke or burning smell If you smell smoke or burning coming from your starter, this could indicate a wiring issue or a failing solenoid.
Starter staying engaged If your starter continues to run even after the engine has started, this could indicate a bad solenoid.

Wiring Diagram for 1986 Mustang Starter Solenoid

Now that you understand the importance of the starter solenoid and the symptoms of a failing one, let’s dive into the wiring diagram for your 1986 Mustang starter solenoid.

The first step in wiring your starter solenoid correctly is to remove the negative cable from your car’s battery to prevent any electrical shocks or accidents. Once you have done this, you can start wiring your solenoid by following the diagram below:

As you can see from the diagram, the wiring for your 1986 Mustang starter solenoid is relatively simple. The large battery cable should be connected to the large post on the solenoid, while the smaller wire should be connected to the small post. It is crucial that you wire your solenoid correctly to prevent any electrical issues from occurring.

Frequently Asked Questions

1. Can I test my starter solenoid to see if it is working correctly?

Yes, you can test your starter solenoid to see if it is working correctly. To do this, you will need a volt-ohm meter (VOM) or a digital multimeter (DMM). First, remove the small wire from your solenoid’s small post. Then, set your VOM or DMM to the continuity setting and connect the positive lead to the solenoid’s small post and the negative lead to the solenoid’s housing. If you get a reading, your solenoid is working correctly. If you do not get a reading, your solenoid may be faulty and need to be replaced.

2. Can a failing starter solenoid damage my car’s electrical system?

Yes, a failing starter solenoid can damage your car’s electrical system. If the solenoid is not wired correctly or is failing, it can cause electrical current to flow where it should not, damaging various components within your car’s electrical system.

3. Can I replace my starter solenoid myself?

Yes, you can replace your starter solenoid yourself if you have some experience with car repairs. However, if you are not comfortable working on your car’s electrical system or are unsure of what you are doing, it is best to consult with a professional mechanic.

4. How often should I replace my starter solenoid?

There is no set timeframe for when you should replace your starter solenoid. However, if you notice any symptoms of a failing solenoid, it is best to have it checked out by a professional mechanic and replaced if necessary.

5. Does the type of oil I use in my car affect the starter solenoid?

No, the type of oil you use in your car should not affect the starter solenoid. However, it is crucial to use the recommended oil for your car to ensure proper engine function and longevity.

Conclusion

As you can see, the starter solenoid is a crucial part of your car’s starting system, and proper wiring is essential to ensure proper function. By following the wiring diagram and tips provided in this article, you can ensure your 1986 Mustang’s starter solenoid is wired correctly, and your car runs smoothly. Remember to always consult with a professional mechanic if you are unsure of what you are doing when it comes to car repairs.
