Review ALL SUN Vintage Dwell Tach Tester Case Untested

The All-Sun GA11377 Dwell Tach Tester is a versatile and essential diagnostic tool for automotive enthusiasts and professional mechanics. This device is specifically designed to test the performance of ignition systems, particularly the dwell angle and RPM of the distributor, coil pack, or crank trigger systems in both gasoline and diesel engines.

The unit features a user-friendly analog design, with a large, easy-to-read dial that displays the test results. The dial is calibrated in degrees for dwell angle measurements and in revolutions per minute (RPM) for tachometer readings. The tester comes with interchangeable probes to accommodate various types of ignition systems, ensuring compatibility with a wide range of vehicles.

The All-Sun GA11377 Dwell Tach Tester boasts a robust construction, with a durable, anodized aluminum housing and high-quality components. The device is built to withstand the rigors of professional use, while also being lightweight and portable, making it an ideal choice for both shop and trackside applications.

To use the tester, simply connect the appropriate probe to the ignition system being tested and turn on the power. The dial will then display the dwell angle or RPM value. The dwell angle test is particularly useful in identifying issues with the ignition system, such as weak or misaligned distributor caps, faulty rotors, or worn out distributor points. The RPM test can be used to verify the functioning of the tachometer or to perform engine performance analysis.

Its ability to accurately and easily test ignition system parameters makes it an essential addition to any garage or toolbox.
