If you’re a golf cart owner, it’s important to know the wiring diagram for your vehicle. This can help you troubleshoot electrical issues, make repairs, or even customize your cart with additional features. In this article, we’ll cover the 1986 EZGO Marathon wiring diagram in detail, including common issues and frequently asked questions.
Wiring Diagram Overview
The wiring diagram for the 1986 EZGO Marathon is separated into several sections, including the battery pack, motor wiring, charger wiring, and key switch wiring. Each section contains specific details about the wires and how they are connected. The diagram is a helpful tool for understanding the electrical system of your golf cart.
Here is a breakdown of the different sections of the wiring diagram:
| Section | Description |
|---|---|
| Battery Pack | Details about the wiring between the battery pack and the motor controller |
| Motor Wiring | Information about the wiring between the motor controller and the motor |
| Charger Wiring | Details about the wiring between the charger and the battery pack |
| Key Switch Wiring | Information about the wiring between the key switch and the motor controller |
Battery Pack Wiring
The battery pack is a critical component of the golf cart’s electrical system. The 1986 EZGO Marathon typically uses six 6-volt batteries wired in series to create a 36-volt system. The battery pack wiring diagram shows the positive and negative leads for each battery, as well as the wiring connections between each battery and the motor controller.
One common issue with battery pack wiring is loose or corroded connections. If the connections aren’t tight, the electrical current won’t flow properly, which can cause the cart to run poorly or not start at all. It’s important to check your battery pack connections regularly and tighten them as needed.
Another issue to watch for is damaged or worn wires. If a wire is frayed or broken, it won’t conduct electricity properly, which can cause electrical issues. It’s important to inspect your wiring regularly and replace any damaged wires as needed.
Motor Wiring
The motor controller is responsible for sending electrical current to the motor, which powers the golf cart. The motor wiring diagram shows how the motor controller is connected to the motor, as well as other components like the forward/reverse switch and the solenoid.
One common issue with motor wiring is a faulty motor controller. If the controller isn’t working properly, the golf cart won’t move or may run erratically. It’s important to check your controller regularly and replace it if it’s not working properly.
Another issue to watch for is worn brushes in the motor. If the brushes are worn down, the motor won’t function properly, which can cause the cart to run poorly or not run at all. It’s important to inspect your motor brushes regularly and replace them as needed.
Charger Wiring
The charger is responsible for recharging the battery pack after each use. The charger wiring diagram shows how the charger is connected to the battery pack, as well as any fuses or other components in the charging system.
One common issue with charger wiring is a faulty charger. If the charger isn’t working properly, the battery pack won’t recharge properly, which can cause the cart to run poorly or not run at all. It’s important to check your charger regularly and replace it if it’s not working properly.
Another issue to watch for is loose or corroded connections in the charging system. If the connections aren’t tight, the electrical current won’t flow properly, which can cause the charger to not work as intended. It’s important to check your charging connections regularly and tighten them as needed.
Key Switch Wiring
The key switch is responsible for turning the golf cart on and off. The key switch wiring diagram shows how the key switch is connected to the motor controller, as well as any other components in the ignition system.
One common issue with key switch wiring is a faulty switch. If the switch isn’t working properly, the golf cart won’t start or may run erratically. It’s important to check your key switch regularly and replace it if it’s not working properly.
Another issue to watch for is worn or damaged wiring in the ignition system. If a wire is frayed or broken, it won’t conduct electricity properly, which can cause the key switch to not work as intended. It’s important to inspect your wiring regularly and replace any damaged wires as needed.
Frequently Asked Questions
What other components should I check regularly besides the wiring?
In addition to checking your wiring regularly, it’s important to inspect other components like the batteries, motor, and controller. These components can wear out over time and may need to be replaced or repaired. It’s also a good idea to keep your golf cart clean and free of debris, which can cause issues with the electrical system.
How can I troubleshoot an electrical issue with my golf cart?
If you’re experiencing electrical issues with your golf cart, the first step is to consult the wiring diagram and check all of the connections and wiring. You can also use a multimeter to test the voltage and current in different parts of the system. If you’re unable to identify and fix the issue on your own, it’s best to consult a professional repair technician.
Can I customize the wiring on my golf cart?
Yes, it’s possible to customize the wiring on your golf cart to add additional features like lights or a stereo system. However, it’s important to do so carefully and with proper knowledge of electrical wiring. If you’re not experienced with electrical work, it’s best to consult a professional technician for assistance.
How often should I check my golf cart’s wiring?
It’s a good idea to check your golf cart’s wiring periodically, especially if you use your cart frequently or in rough terrain. How often you check your wiring will depend on how often you use your cart and how rough the terrain is. As a general rule, it’s a good idea to inspect your wiring at least once every six months.
