The Battery Guardian opens and connects the two 5/16” copper terminals by means of a sliding contact. Each time the Sig terminal is momentarily switched to ground, the contact instantly switches, and the Battery Guardian changes the ON/OFF state. The Battery Guardian remains in the On or Off state, without coil power


The BG is a Battery Disconnect (BD) but also includes an automatic low-voltage disconnect. When it senses the levels are getting low it will automatically disconnect to prevent further draining.

The BG AutoSelect (00-10041-460) is a cross between a BD and a BG and works with a 3-position Rocker Switch: On, Off, and Auto.

In the On or Off position, it works like a BD. In the Auto position, it works like a BG.
