1970 Harley Davidson Golf Cart Wiring Diagram: Everything You Need to Know

If you own a 1970 Harley Davidson golf cart, you may be wondering how to properly wire it. Without a wiring diagram, it can be difficult to navigate the electrical system of your golf cart. In this article, we will discuss everything you need to know about the 1970 Harley Davidson golf cart wiring diagram. We will provide step-by-step instructions and detailed explanations to help you successfully wire your golf cart.

What is a Wiring Diagram?

A wiring diagram is a visual representation of the electrical system of a machine. It shows each component and how it connects to other components in the system. A wiring diagram can be helpful in troubleshooting electrical problems and in understanding how the electrical system works.

For the 1970 Harley Davidson golf cart, the wiring diagram will show the placement of each wire and connector. It will also show the electrical components, such as the battery, solenoid, and motor, and how they connect to the wiring system. With this information, you can confidently wire your golf cart.

Components of the Wiring System

Before we dive into the wiring diagram, let’s take a moment to understand the components of the wiring system. The wiring system on a 1970 Harley Davidson golf cart consists of the following components:

  1. Battery
  2. Solenoid
  3. Forward/Reverse Switch
  4. Key Switch
  5. Motor
  6. Controller
  7. Charger

Each of these components plays a crucial role in the electrical system of the golf cart. Understanding how they work together is key to properly wiring your golf cart.

Wiring Diagram Overview

Now that we’ve covered the components of the wiring system, let’s take a look at the wiring diagram. The 1970 Harley Davidson golf cart wiring diagram is divided into several sections. Each section represents a different area of the wiring system.

The wiring diagram also includes color codes for each wire. These color codes make it easier to identify each wire and ensure that they are properly connected.

Battery and Solenoid

The first section of the wiring diagram shows the battery and solenoid. The battery is connected to the solenoid via two wires. One wire is connected to the positive terminal of the battery, while the other wire is connected to one of the large terminals on the solenoid.

The other large terminal on the solenoid is connected to the motor. Two small wires are also connected to the solenoid. One wire runs from the key switch to the small terminal on the solenoid, while the other wire runs from the forward/reverse switch to the small terminal on the solenoid.

Forward/Reverse Switch

The next section of the wiring diagram shows the forward/reverse switch. The forward/reverse switch is connected to the solenoid via two wires. One wire runs from the small terminal on the solenoid to the forward position on the switch, while the other wire runs from the small terminal on the solenoid to the reverse position on the switch.

The forward/reverse switch also has two large terminals. One wire runs from the positive terminal of the battery to the forward position on the switch, while the other wire runs from the positive terminal of the battery to the reverse position on the switch.

Key Switch

The third section of the wiring diagram shows the key switch. The key switch is connected to the solenoid via one wire. This wire runs from the small terminal on the solenoid to the key switch.

The key switch also has two large terminals. One wire runs from the positive terminal of the battery to the key switch, while the other wire runs from the key switch to the controller.

Motor and Controller

The fourth section of the wiring diagram shows the motor and controller. The motor is connected to the solenoid, while the controller is connected to the key switch and the motor.

The controller is responsible for controlling the speed and direction of the motor. It receives signals from the key switch and the forward/reverse switch to determine how to control the motor. By properly wiring the controller, you can ensure that your golf cart operates smoothly and safely.

Charger

The final section of the wiring diagram shows the charger. The charger is connected to the battery via two wires. One wire runs from the positive terminal of the battery to the charger, while the other wire runs from the negative terminal of the battery to the charger.

Make sure that you properly wire the charger to your golf cart. This will ensure that your battery is charged properly and that your golf cart is always ready for use.

FAQ

What wire should I use to connect the battery to the solenoid?

You should use a 6-gauge wire to connect the battery to the solenoid. This wire should be at least 18 inches long.

How do I know if my solenoid is working properly?

You can test your solenoid by using a multimeter. Set the multimeter to ohms and touch the probes to the two large terminals on the solenoid. The multimeter should read 0 ohms. If it reads a higher resistance, your solenoid may be faulty.

What type of fluid should I use in my golf cart battery?

You should use distilled water to fill your golf cart battery. Do not use tap water or any other type of fluid.

Can I use regular automotive wire to wire my golf cart?

No, you should not use regular automotive wire to wire your golf cart. Golf carts require specific types of wire that are designed for their electrical systems. Using the wrong wire can result in electrical problems or even a fire.

What should I do if I’m having trouble wiring my golf cart?

If you’re having trouble wiring your golf cart, consult the wiring diagram and double-check that each wire is connected properly. If you’re still having trouble, consider consulting a professional mechanic or electrician.

Conclusion

Wiring a 1970 Harley Davidson golf cart may seem like a daunting task, but with the right wiring diagram and some basic electrical knowledge, it can be done successfully. By following the steps outlined in this article and consulting the wiring diagram, you can ensure that your golf cart is wired properly and operates safely and efficiently.
