Vehicles have many control units that consume a lot of electrical power. These units control their own system based on information from various sensors. It is important to have a stable power supply because the various sensors provide a lot of different information. The sensor (A) is attached to the battery (-) terminal. It transmits voltage, current and temperature information from the battery to the ECM. The ECM commands the charging voltage for the output cycle based on these signals.
