### Pros and Cons of buying a Harley-Davidson Part Number 68437-99 (Shorting Bar Flasher)

1. **Compatibility** This part is designed specifically for Harley-Davidson motorcycles, ensuring a proper fit with minimal modifications required. It is likely intended for models that use a shorting bar flasher system, which is common in older Harley-Davidson electrical setups (particularly pre-1990s models).

2. **Functionality** The shorting bar flasher is a critical component in the ignition system of many Harley-Davidsons. It helps manage the electrical flow to the ignition coil, ensuring proper spark generation. A functional flasher is essential for reliable starting and smooth engine operation.

3. **Ease of Installation** As an OEM (Original Equipment Manufacturer) part, it should be straightforward to install, especially if you have basic mechanical or electrical experience. The part is likely designed to plug into existing wiring harnesses without requiring extensive modifications.

4. **Reliability** Harley-Davidson parts, especially OEM components, are generally built to last and are designed to withstand the demands of motorcycle use. A high-quality flasher can reduce the risk of electrical failures or intermittent issues.

5. **Preventative Maintenance** Replacing a worn-out or failing flasher can prevent more significant electrical problems, such as a dead battery, ignition failure, or damage to other components like the ignition coil or wiring.

6. **Authentic Performance** Using an OEM part ensures that the motorcycle retains its original performance characteristics. Aftermarket parts may offer improvements but could also introduce compatibility issues or void warranties.

---

1. **Age and Wear** If the motorcycle is older, the flasher may already be nearing the end of its lifespan. Shorting bar flashers, like many mechanical or electrical components, can degrade over time due to heat, vibration, and exposure to the elements. Replacement may be necessary sooner rather than later.

2. **Cost** Harley-Davidson OEM parts can be expensive, especially for older models. The price of the flasher itself, along with potential labor costs if you re not installing it yourself, may be a significant investment.

3. **Limited Availability** Depending on the age of your Harley-Davidson, finding OEM parts like this flasher may be challenging. Harley-Davidson has phased out some older parts, and sourcing them may require purchasing from specialty dealers, salvage yards, or third-party suppliers, which could affect availability and authenticity.

4. **Potential for Counterfeit Parts** If you purchase from non-authorized sellers, there is a risk of receiving counterfeit or low-quality replicas. Counterfeit parts may fail prematurely or not function as intended, leading to further issues.

5. **Compatibility Issues** While this part is likely designed for specific Harley-Davidson models, there is always a chance of misalignment or incompatibility if the motorcycle has been heavily modified or if the wiring harness has been altered. Double-checking the model and year of your motorcycle is crucial.

6. **Learning Curve** If you re not familiar with motorcycle electrical systems, diagnosing whether the flasher is the root cause of an issue (e.g., ignition problems, flickering lights) can be difficult. You may need to consult a mechanic or perform additional troubleshooting.

7. **Environmental Factors** Motorcycle electrical components are exposed to moisture, dust, and extreme temperatures. Even a new flasher may fail prematurely if not properly sealed or if the surrounding wiring is damaged.

The Harley-Davidson 68437-99 shorting bar flasher is a vital and reliable component for maintaining the electrical integrity of compatible Harley-Davidson motorcycles. Its primary advantage lies in its compatibility, functionality, and reliability as an OEM part. However, the decision to purchase it should consider factors such as the age of your motorcycle, the cost of the part, potential availability issues, and your own mechanical expertise.

If your motorcycle is experiencing ignition-related problems (e.g., no spark, erratic starting, or flickering lights), replacing the flasher is a logical and preventative step. However, if the motorcycle is very old or has been heavily modified, you may need to verify compatibility and consider whether an aftermarket alternative or a full electrical system overhaul is more appropriate.

---

1. **Verify Compatibility** Confirm that the 68437-99 part number is correct for your specific Harley-Davidson model and year. Cross-reference it with your motorcycle s service manual or consult a Harley-Davidson dealer to avoid purchasing the wrong part.

2. **Diagnose the Issue** Before replacing the flasher, ensure that the problem is indeed related to the shorting bar flasher. Symptoms like no spark, a dead battery, or intermittent electrical issues could also stem from other components (e.g., ignition switch, wiring, or coil). A multimeter or consultation with a mechanic can help isolate the problem.

3. **Purchase from a Trusted Source** Buy the part from an authorized Harley-Davidson dealer, a reputable motorcycle parts supplier, or a salvage yard with a good return policy. Avoid purchasing from unverified sellers to ensure you receive a genuine OEM part.

4. **Consider Aftermarket Alternatives** If the part is difficult to find or expensive, explore aftermarket options that are compatible with your motorcycle. Brands like *Harley-Davidson Performance Parts* or *Evinrude* (for some models) offer alternatives, though you should research their reliability and compatibility thoroughly.

5. **Install Properly** If you re not experienced with motorcycle electrical work, consider having a professional install the part. Improper installation can lead to further issues or void any warranty on the part.

6. **Maintain the System** After replacement, monitor the motorcycle s electrical performance. Regularly inspect the wiring, connections, and other components to ensure everything remains in good working order. Consider upgrading to a more modern ignition system if your motorcycle is very old, as older systems can be prone to failure.

**Final Verdict:** If the part is necessary for your motorcycle s operation and you ve confirmed its compatibility, purchasing the Harley-Davidson 68437-99 shorting bar flasher is a sound investment. However, weigh the cost against the potential benefits and consider whether a more comprehensive electrical upgrade might be more cost-effective in the long run. For most riders, replacing a failing flasher is a straightforward and worthwhile maintenance task.
