When it comes to repairing and modifying your 87 Jeep Wrangler, knowing the wiring diagram is crucial. The wiring of your jeep Wrangler controls all the electrical components and without it, your vehicle won’t function properly. In this article, we will be discussing the basics of the 87 Jeep Wrangler wiring diagram, how to read and troubleshoot it, and common FAQ.
Basics of the 87 Jeep Wrangler Wiring Diagram
The 87 Jeep Wrangler wiring diagram is a schematic representation of the electrical components and their connections in your Jeep. The diagram shows how all the wires are interconnected and where they are located.
The Jeep Wrangler has a simple wiring system, and it’s broken down into three main categories. These categories include the power distribution center, the fuse block, and the wiring harness. Let’s discuss these categories briefly below.
Power Distribution Center
The power distribution center is the central location of all the electrical components. It’s where the battery, starter, alternator, and other essential parts are connected. The power distribution center is located under the hood of your Jeep.
Fuse Block
The fuse block is the location of all the electrical fuses. The fuse block is usually located under the dashboard. The fuses protect the electrical components from being damaged in case of an electrical overload.
Wiring Harness
The wiring harness is a set of wires that are bundled together and routed throughout the Jeep. It connects all the electrical components together, ensuring that they work correctly.
How to Read and Troubleshoot the 87 Jeep Wrangler Wiring Diagram
Reading and troubleshooting the wiring diagram is crucial when it comes to repairing or modifying your jeep. Below are some basic steps that you can use to read and troubleshoot the wiring diagram.
Step 1: Understand the Symbols
The first step in reading the Jeep Wrangler wiring diagram is to understand the symbols. The symbols represent the different electrical components, such as the battery, alternator, and fuses.
The key to understanding the symbols is to read the legend or key in the diagram. The legend or key will explain what each symbol means and how to interpret it.
Step 2: Identify Problem Areas
The next step is to identify the problem areas in the wiring diagram. Look for any wires that are disconnected, frayed, or corroded. These areas may indicate a problem with the electrical components or a wiring issue.
Step 3: Trace the Wires
Once you’ve identified the problem areas, you need to trace the wires to see where they lead. Use the wiring diagram to follow the wires’ path and see where they connect to other components.
Tracing the wires allows you to identify any other areas that may be causing the problem. For example, if a wire is disconnected, tracing it may reveal that it was unplugged from the power distribution center or the fuse block.
Step 4: Test the Components
Once you’ve traced the wires, you can test the components to see if they’re functioning correctly. Use a multimeter to test the components’ electrical continuity and to check for any shorts or opens in the wiring.
Testing the components allows you to identify any components that need to be replaced or repaired.
