Description and Operation

Description

Vehicles have many control units that consume more electrical power. These units control their own systems based on information from various sensors. It is important to maintain a stable power supply, since different sensors provide different information. The battery sensor is installed on the negative (-) battery terminal. It transmits battery voltage and current and temperature information to the ECM. The ECM controls the generator output voltage duty cycle based on these signals.
