Power Requirements
The
BCM has two main power feeds (high and low current), and two main grounds. The low power feed (battery 1) is used to provide power for the BCMs logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights, etc.). Operating current at the BCMs battery should not exceed
3.0 amperes at battery 1, and
7.5 amperes (for
2 seconds) at battery 2 while the BCM is awake, and
2.5 milliamps when the BCM is asleep. For most BCM functions, the BCM will operate properly with a system voltage of
9.0 - 16.0 volts. If system voltages exceed
16.0 volts the BCM will provide protection by disabling certain functions that may damage due to higher than normal system voltages.
