How To Wire A 24 Volt Starter

By | December 15, 2022



As technology continues to advance, so do the systems and components that power our vehicles. One such component is the starter, which is responsible for initiating the engine's combustion process. While most vehicles run on a 12-volt system, some larger and more powerful engines require a 24-volt starter. In this article, we will discuss how to properly wire a 24-volt starter, ensuring that your vehicle is ready to start with a simple turn of the key.

First and foremost, it is crucial to understand the difference between a 12-volt and 24-volt starter. A 12-volt starter has two terminals, whereas a 24-volt starter has three. The additional terminal on the 24-volt starter is known as the "jumper post," and it is used to connect the two batteries in a series. This creates a 24-volt power supply, providing the necessary voltage to crank larger engines. Now that we have an understanding of the components let's dive into the wiring process.

To begin, you will need to gather the necessary tools and materials, including a wrench, wire cutters, electrical tape, and a wiring diagram for your specific vehicle. Next, disconnect the negative cables from both batteries and remove the old starter if necessary. Then, attach the positive cable from the first battery to the main terminal on the starter. From there, take the positive cable from the second battery and connect it to the jumper post on the starter. Finally, connect the negative cable from the first battery to the ground post on the starter, and the negative cable from the second battery to the vehicle's frame.

In conclusion, wiring a 24-volt starter may seem daunting, but with the right tools and knowledge, it can be a straightforward process. Remember to always consult a wiring diagram and double-check your connections before starting your vehicle. By following these steps, you can ensure that your vehicle's starter is properly wired, providing a reliable and powerful start every time.
