Harley Davidson is a well-known brand that has been associated with quality motorcycles for over a century. But, did you know that they also produced golf carts? The 1974 Harley Davidson Golf Cart is a vintage machine that requires proper maintenance and care to function effectively. One of the essential aspects of maintaining a golf cart is to have a clear understanding of its wiring diagram. In this article, we will take a closer look at the wiring diagram of the 1974 Harley Davidson Golf Cart.
Overview of Harley Davidson Golf Cart Wiring Diagram
The Harley Davidson Golf Cart is powered by a 2-cycle engine and a 12-volt electrical system. The electrical system comprises different components that work together to ensure the proper functioning of the cart. The wiring diagram is a visual representation of the electrical system, showing the different components and their interconnections.
The wiring diagram of the 1974 Harley Davidson Golf Cart consists of several wires and connections, including the main battery cables, starter/generator cables, solenoid, ignition switch, and key switch. Understanding the diagram is critical for troubleshooting and fixing any electrical issues that may arise.
Main Battery Cables
The main battery cables are the heart of any electrical system. In the case of the 1974 Harley Davidson Golf Cart, there are two main battery cables – the positive and negative cables. The positive cable connects the positive terminal of the battery to the solenoid, while the negative cable connects the negative terminal of the battery to the frame of the cart.
The main battery cables should be checked regularly for corrosion or damage. Corrosion can cause a low voltage issue, while damage to the cables can cause a complete electrical failure. It is recommended to replace damaged cables immediately and clean corroded cables with a wire brush and baking soda solution.

| Cable Name | Specification |
|---|---|
| Positive Cable | 4-gauge, 36-inch long |
| Negative Cable | 4-gauge, 24-inch long |
Starter/Generator Cables
The starter/generator cables are responsible for delivering the electrical charge from the starter/generator to the battery. The positive cable connects the starter/generator to the solenoid, while the negative cable connects the starter/generator to the frame of the cart.
The starter/generator cables should also be checked regularly for corrosion or damage. If either of the cables is damaged, it can affect the charging of the battery and the operation of the cart.
