A. Introduction
The 139155 DS starter solenoid is a critical component in starting the engine of Harley-Davidson motorcycles. Replacing a faulty starter solenoid can ensure a smooth riding experience. Let's examine the pros and cons of purchasing this part.
B. Pros of Buying a 139155 DS Starter Solenoid
1. Improved Starting: A new starter solenoid ensures a reliable start, eliminating the challenge of attempting to turn over a engine with a weak or failing solenoid.
2. Enhances Battery Life: If the starting issue is due to a malfunctioning starter solenoid, it can drain the battery. Replacing the solenoid can help prevent unnecessary battery drain.
3. Smoother Operation: A functioning starter solenoid ensures an efficient electrical connection during starting, reducing jerkiness and vibrations.
4. Cost-Effective: In the long run, replacing a faulty starter solenoid is more cost-effective than replacing the entire starter motor or dealing with continuous battery replacement.
C. Cons of Buying a 139155 DS Starter Solenoid
1. Minimal Savings: The cost of a new starter solenoid can still be significant, which might discourage some riders from making this investment, especially if they are experiencing multiple issues with their motorcycle.
2. Installation Complexity: The starter solenoid is located near the motor (stator), and reaching it for replacement might be challenging for those without mechanical skills or tools.
3. Time-Consuming: Installing a new starter solenoid can take longer than a typical repair, which might be a deterrent for those who are time-constrained.
D. Conclusion
Despite the cons, investing in a 139155 DS starter solenoid offers numerous benefits, such as improved starting reliability, extended battery life, and smoother operation. While the upfront cost and installation complexity might pose challenges, the long-term savings and enhanced riding experience justify the investment for many Harley-Davidson riders.
E. Recommendation
If you are having difficulty starting your Harley-Davidson motorcycle or experiencing issues that suggest a malfunctioning starter solenoid (such as a weak or slow start), consider investing in a new 139155 DS starter solenoid. Ensure that you source a high-quality product from a reputable supplier and ensure that the installation is performed by a competent mechanic or yourself, if you have the necessary skills. The improved starting reliability and long-term savings will ultimately provide a more enjoyable riding experience.
