Why Yamaha Rhino 660 Replace Solenoid Replacement is Necessary
When I first noticed that my Yamaha Rhino 660 was struggling to start, I immediately suspected a problem with the solenoid. After some research and troubleshooting, I realized that replacing the solenoid was not just a good idea; it was essential for restoring the functionality of my vehicle. The solenoid plays a crucial role in the starting system by acting as a relay that engages the starter motor. If it’s malfunctioning, you’ll find yourself dealing with intermittent starting issues or even complete failure to start.
In my experience, ignoring a faulty solenoid can lead to more significant problems down the line. A bad solenoid can put extra strain on the battery and starter motor, potentially causing them to wear out faster. I learned this the hard way when I tried to delay the replacement and ended up needing to replace both the battery and starter, which turned into a much bigger expense. By proactively replacing the solenoid, I was able to save myself both time and money, not to mention the frustration of being stranded.
Furthermore, the peace of mind that comes with knowing my Yamaha Rhino 660 will start reliably every time is invaluable. I love taking it out for adventures, and the last thing I want
My Buying Guides on Yamaha Rhino 660 Replace Solenoid Replacement

This little component plays a crucial role in starting the engine, so I want to share my experience and insights with you. Here’s a comprehensive buying guide on Yamaha Rhino 660 solenoid replacement.
Understanding the Solenoid
Before I dive into the buying options, let’s quickly cover what a solenoid does. The solenoid is an electromechanical device that engages the starter motor when I turn the key in the ignition. If my Rhino doesn’t start or makes a clicking sound, it’s often a sign that the solenoid may need to be replaced.
Signs of a Failing Solenoid
Recognizing the signs of a failing solenoid is crucial for timely replacement. Here are a few symptoms I’ve experienced:
- Clicking Noise: When I turn the key and hear a clicking sound but the engine doesn’t start.
- Engine Won’t Crank: If my Rhino is completely unresponsive to the ignition.
- Intermittent Starting: Sometimes it starts, other times it doesn’t—definitely a red flag.
Choosing the Right Replacement Solenoid
When it came time to find a replacement solenoid, I focused on a few key aspects:
1. Compatibility
I made sure to check that the solenoid was compatible with my Yamaha Rhino 660. Always verify the part number and cross-reference with my Rhino’s specifications to avoid any mismatches.
2. Quality and Durability
I learned that not all solenoids are created equal. I prioritized brands known for their quality. After some research, I found that OEM (Original Equipment Manufacturer) parts tend to be more reliable than generic replacements, although they can be pricier.
3. Price
While I was willing to invest in a good quality solenoid, I also compared prices across different retailers. I found that prices can vary significantly, so shopping around helped me find a balance between quality and affordability.
Where to Buy
I explored various places to purchase my solenoid:
- Local Dealerships: They typically have OEM parts, but the prices can be high.
- Online Retailers: Websites like Amazon, eBay, and specialized ATV parts sites often have competitive prices and a wide selection. I appreciated the convenience of reading reviews from other customers.
- Auto Parts Stores: Local auto parts stores sometimes carry compatible solenoids, and I liked being able to see the part in person before buying.
Installation Tips
Once I had my new solenoid, I was ready to install it. Here are some tips based on my experience:
- Disconnect the Battery: Safety first! I always disconnect the battery before working on my Rhino.
- Locate the Solenoid: It’s usually located near the starter motor. I made sure to have a manual handy for guidance.
- Remove Old Solenoid: I carefully unscrewed and detached the old solenoid, taking note of how it was connected.
- Install the New Solenoid: I followed the reverse process to connect the new solenoid, ensuring everything was tight and secure.
- Reconnect the Battery: After everything was installed, I reconnected the battery and tested the ignition.
Conclusion
Replacing the solenoid on my Yamaha Rhino 660 was a straightforward process, and finding the right replacement made all the difference. By focusing on compatibility, quality, and price, I was able to ensure that my Rhino would start reliably. If you’re experiencing any starting issues, I highly recommend checking the solenoid and considering a replacement if needed. Happy riding!
