Car Digital Voltage Stabilizer Universal Electric Voltage Regulator Rectifier with Earth Ground Cables and Mounting Hardware Kit Features: Low speed torque is increased, the speed is increased, and the climbing is powerful. The throttle response is more direct and obvious than before. Ignition performance is rapidly improved, the ignition is easier, and the ignition efficiency is improved. Power supply can be stabilized after installation. Reduce the interference and noise of the sound quality. The unique power storage function pinches the reverse current. Extend battery life. Used with the ground wire, the entire vehicle body circuit will flow more stably. Product Installation: 1. Open the hood and find the positive and negative poles of the battery. The positive pole is red and the negative pole is black. The battery is also marked. 2. Use the No. 10 pick to loosen the positive pole of the battery.
