Onan Generator Starter Solenoid Wiring: (Solution) In 2023

Starting an Onan generator can be quite challenging, especially if you are not familiar with its wiring. One of the most important components of the Onan generator is the starter solenoid, which plays a critical role in the generator’s starting process.

In this article, we will discuss everything you need to know about the Onan generator starter solenoid wiring, including how to troubleshoot it, how to replace it, and much more.

What is an Onan Generator Starter Solenoid?

An Onan generator starter solenoid is a small electronic device that is responsible for connecting and disconnecting the battery to the starter motor.

The starter solenoid is a crucial component of the starting process, as it allows the starter motor to receive the necessary voltage to turn the engine over.

How Does an Onan Generator Starter Solenoid Work?

When you turn the key to start your Onan generator, a signal is sent to the starter solenoid, which connects the battery to the starter motor.

This causes the starter motor to turn the engine over, which then starts the generator. Once the generator is running, the starter solenoid disconnects the battery from the starter motor to prevent damage to the generator’s electrical system.

Common Problems with Onan Generator Starter Solenoid Wiring

The starter solenoid is a small, yet important component of the Onan generator’s starting system. Like any other electronic device, it can experience various problems that can prevent it from working properly.

Some of the most common problems with Onan’s generator starter solenoid wiring include:

• Loose or corroded connections
• Worn out contacts
• Damaged wiring
• Faulty solenoid coil
• Low battery voltage

Troubleshooting Onan Generator Starter Solenoid Wiring

If you are experiencing problems with your Onan’s generator starter solenoid wiring, there are several steps you can take to troubleshoot the issue. Some of these steps include:

• Checking the battery voltage
• Inspecting the wiring for damage or corrosion
