In 1986, Ford introduced a new version of their iconic F150 truck. With its tough and rugged design, powerful engine, and advanced features, the 1986 Ford F150 quickly became a favorite among truck enthusiasts. However, one issue that plagued many owners was the ignition switch wiring. As the years passed, this problem only worsened, leaving many frustrated owners wondering how to fix it. In this article, we will take a closer look at the 1986 Ford F150 ignition switch wiring diagram and provide some helpful tips on how to troubleshoot and resolve this common issue.

The main issue with the 1986 Ford F150 ignition switch wiring is that over time, the wires can become corroded or loose, causing problems with starting the vehicle. This can be incredibly frustrating and inconvenient, especially if you rely on your truck for work or daily transportation. The first step to resolving this issue is to carefully study the wiring diagram for your specific truck model. This will give you a better understanding of how the system works and help you pinpoint the source of the problem.

To begin troubleshooting, start by checking all the connections and wires in the ignition switch circuit. Make sure they are all secure and free of any corrosion or damage. If you find any damaged wires or connections, it is best to replace them as soon as possible. You can also use a voltmeter to test the power supply and make sure it is reaching the starter when the key is turned. If the power supply is weak or not reaching the starter at all, you may need to replace the ignition switch. It is important to note that if the ignition switch is not the problem, further diagnostics may be necessary to determine the root cause.

In conclusion, while the 1986 Ford F150 ignition switch wiring may have been a source of frustration for many owners, it is a relatively common issue that can be easily resolved with the right knowledge and tools.
