Each gauge comes calibrated at the factory and includes a factory adjustment certificate for accuracy verification. The gauge's face also features a backlit light for improved visibility during low-light conditions.

The kit includes the Tach-Dwell-Points Gauge, a 15-foot (4.57m) wiring harness with a traditional Viton seal, a high-quality gasket, and instructions for easy installation. This Stewart Warner instrument is an excellent addition to any vehicle dashboard, providing essential information for optimizing engine performance and maintaining a well-tuned ignition system.

Stewart Warner 27486 Tach-Dwell-Points Gauge: A Detailed Analysis

The Stewart Warner 27486 Tach-Dwell-Points Gauge is a versatile automotive gauge designed for monitoring engine RPM and dwell angle in race applications. In this analysis, we will discuss the advantages and disadvantages of purchasing this gauge to help you make an informed decision.

1. Multi-functional: This gauge measures both engine RPM and dwell angle, providing valuable data for fine-tuning the ignition system in high-performance applications.

2. Durable Construction: Stewart Warner gauges are known for their robust, heavily instrumented mechanical contents with a brass housing that ensures a long lifespan.

3. Improves performance: By monitoring the dwell angle (the length of time that the distributor's contacts are closed to build voltage for the spark plugs), this gauge allows drivers to optimize ignition timing and fuel delivery for improved engine performance.

4. Customizable: An optional low-profile bezel is available for a flush installation, and various mounting options make this gauge suitable for a range of vehicle applications.

5. Useful in various driving environments: It can be beneficial for street driving and also comes handy in racing situations where fine-tuning is crucial for optimizing engine performance.

1. Limited compatibility: This gauge is primarily designed for specialized applications and may not be directly compatible with all vehicles. Therefore, it may require additional components such as a voltage regulator or an external power source, which may add to the cost.

2. Complex setup: Setting up this gauge might be a challenge for individuals without extensive automotive experience, as it requires precise calibration of the cam position sensor and dwell angle sensor for accurate operation.

3. Expensive: Compared to other classical gauges in the Stewart Warner product line, the 27486 Tach-Dwell-Points Gauge is relatively pricier due to its advanced features.

The Stewart Warner 27486 Tach-Dwell-Points Gauge offers a unique combination of multi-functionality, durability, and performance improvements in specialized applications, making it well worth considering. However, its complex installation process, limited compatibility, and higher price may not appeal to casual or occasional drivers. If you're a serious racer or someone looking to fine-tune the ignition system on a high-performance vehicle, this gauge might be an excellent investment. On the other hand, if you're looking for a more straightforward and affordable gauge for regular street driving, other models in the Stewart Warner line might be more suitable.

Before making a decision, carefully assess your specific automotive needs and ensure this gauge is compatible with your application. If you're a serious racer aiming to optimize engine performance, the Stewart Warner 27486 Tach-Dwell-Points Gauge could be an excellent investment. However, if you're looking for a more straightforward solution for regular street driving, consider exploring other options within Stewart Warner's extensive gauge product line.

Details:

I am a retired elementary school math/science teacher, and try to keep my prices reasonable as know what its like live on budget. The plastic lens is still clear and legible. Now for some other stuff. The switch seems to work in all positions.

I only ship to the CONUS sorry HI and AK Polynesia etc. My goal is to NEVER charge more for shipping than I pay. Vintage Stewart Warner Dwell-Tach-Points gauge. I live in a smoke-free home.

So, my stuff should not stink. I just do this to supplement my extraordinarily high retirement pay brouhaha. This looks great, and the needle moves freely as it should, but I can't test this on my modern truck. I don't charge anything for the materials use shipping.
