Review KING Original Vintage Generator Voltage Regulator Tester Old Garage Display #15 fits 2015

The King G-104 Generator Voltage Regulator Tester is an essential tool for any garage or workshop, designed to help diagnose issues with your vehicle's charging system. This user-friendly device is capable of testing both 12V and 24V generator voltage regulators, making it a versatile addition to your toolbox.

The tester features a clear and easy-to-read digital display, which shows the voltage input, voltage output, and the status of the regulator. The generator voltage regulator test function allows you to check if the regulator is functioning correctly by measuring the voltage drop across the internal shunt resistor. This feature can help identify issues such as a faulty regulator, open circuit, or shorted wiring.

Additionally, the King G-104 includes a load test function, which simulates the load on the battery by drawing a specific amount of current. This test can help determine if the charging system is able to maintain the battery voltage under load. The load test function can be set to 12V, 14.4V, or 15V, depending on your vehicle's requirements.

The tester also includes a diode test function, which can help diagnose issues with the rectifier diodes in the charging system. This function measures the voltage and current in both directions, allowing you to check for reverse current flow, which can indicate a diode failure.

The King G-104 Generator Voltage Regulator Tester is compact and portable, with a rugged design that can withstand the demands of a garage or workshop environment. It comes with a set of test leads and a carrying case, making it easy to transport and store. The tester also includes a safety warning system, which alerts you if the battery voltage is too low or if there is a short circuit.

Overall, the King G-104 Generator Voltage Regulator Tester is a must-have tool for anyone who wants to ensure their vehicle's charging system is functioning correctly. Its versatile features, clear digital display, and rugged design make it a reliable and effective solution for diagnosing and repairing charging system issues.
