Jeep Cherokee is one of the most popular SUVs in the world. It was first introduced in 1974 and has been sold with different generations since then. The 1990 Jeep Cherokee is a third-generation model that was produced between 1984 and 2001. One of the most important parts of any vehicle is its ignition system. In this article, we will discuss the 1990 Jeep Cherokee ignition wiring diagram.
What is an ignition system?
The ignition system in a vehicle is a complex system that is responsible for starting and stopping the engine. It is made up of several components that work together to produce a spark, which ignites the fuel in the engine. The ignition system consists of the ignition switch, battery, starter motor, distributor, spark plugs, and ignition coil.
In this article, we will focus on the ignition wiring diagram for the 1990 Jeep Cherokee.
What is an ignition wiring diagram?
An ignition wiring diagram is a schematic representation of the electrical connections that make up the ignition system of a vehicle. It shows the wiring connections between the battery, ignition switch, starter motor, distributor, ignition coil, and spark plugs. It is used by mechanics and car enthusiasts to diagnose and troubleshoot problems in the ignition system.

FAQ
What is the purpose of the battery in the ignition system?
The battery is responsible for providing power to the ignition system. It provides the initial power needed to start the engine and the ongoing power needed to keep it running.
What is the role of the ignition switch?
The ignition switch is responsible for controlling the flow of power to the starter motor. When the switch is turned to the “ON” position, it sends power to the starter motor, which turns the engine over.
What is the function of the starter motor?
The starter motor is responsible for turning the engine over. It uses electrical power from the battery to spin the engine until it starts running on its own.
What is the role of the distributor?
The distributor is responsible for distributing power to the spark plugs. It is a rotating device that sends power to each spark plug in turn, causing them to fire in the correct sequence.
What is the function of the ignition coil?
The ignition coil is responsible for producing high voltage for the spark plugs. It takes low voltage power from the battery and transforms it into high voltage that can ignite the fuel in the engine.
Conclusion
The ignition system is a crucial part of any vehicle, including the 1990 Jeep Cherokee. The ignition wiring diagram is an essential tool for diagnosing and troubleshooting problems with the system. By understanding the wiring connections between the battery, ignition switch, starter motor, distributor, ignition coil, and spark plugs, you can keep your Jeep Cherokee running smoothly for years to come.
