Charging System Test

The Charging system is an essential part of the vehicle. The purpose of the charging system is to maintain the charge of the vehicle’s battery and provide a source of electricity while the engine is running. The heart of the charging system is the Alternator or sometimes called Generator. The Alternator is a generator that produces Alternating Current (AC), which is then converted into Direct Current (DC) by diodes inside the alternator. Normal charging Voltage is between 13.6V and 14.8V. When the charging system is not working properly, a battery light will light up on the instrument cluster warning the driver that there is an issue. When the charging system is faulty, a charge test is one of the first diagnostic procedures performed. Technicians typically pull out their DMM or other tools to perform this test.

Charge test is one of many new tests included in EZ Diagnostics mode of the Power Probe 3EZ. When selecting a charge test in the EZ Diagnostics section, a QR code will display. Once scanning the QR code with a smart device, a video will guide the user on to perform a charge test. With this feature, you can measure and monitor the diode rectifier ripple voltage in a charging system while the engine is running. The tool will also notify the user if the ripple voltage is within spec or not, letting you know whether the Alternator is operating properly or not.
