Godiag GT106 Plus 24V to 12V Power Adapter is an upgraded 3-in-1 diagnostic adapter designed to bridge the gap between 12V diagnostic scanners and 24V heavy-duty vehicles. While standard scanners are designed for passenger cars, many trucks, buses, and construction machines use 24V systems that can fry a 12V tool. The GT106 Plus safely converts this voltage and adds advanced maintenance testing for injectors and relays.
