Onan Ignition Coil Wiring Diagram

If you’re looking for a detailed tutorial on how to wire up an Onan coil, then you’ve come to the right place. Onan coils are used in a variety of applications and are a reliable source of electricity. In this article, we’ll provide you with an easy-to-follow Onan coil wiring diagram so you can get your project done right the first time.

Understanding Onan Coil Wiring

Onan coils are basically electrical devices that generate an electrical current when a coil is energized. The electrical current is then used to power any number of appliances or tools. Onan coils come in a variety of sizes and shapes, but the basic wiring remains the same. Understanding how to wire an Onan coil is fairly straightforward, so let’s get started.

Step-by-Step Onan Coil Wiring

The first step in wiring an Onan coil is to determine the voltage of the coil. This can be done by looking at the rating label on the side of the coil. Once you’ve determined the voltage, you can connect the two terminals of the coil to the appropriate circuit breaker in your home’s main electrical box. If the two terminals are labeled “O” and “L”, then “O” should be connected to the hot wire and “L” should be connected to the neutral wire.

The next step is to connect the appropriate number of wires from the circuit breaker to the Onan coil. Typically, you’ll need two wires for a 12-volt system and three wires for a 24-volt system. Once all the wiring is connected, it’s time to test the Onan coil. Turn on the circuit breaker and if the Onan coil is wired correctly, it should start up and begin producing electricity.


Wiring an Onan coil is a simple process and can be done by anyone with basic electrical knowledge. Be sure to consult an electrician if you’re not sure how to proceed. With the help of this Onan coil wiring diagram, you should have no trouble getting your Onan coil up and running in no time.
