Operation:

The Battery Guardian Auto opens and connects the two 5/16” copper terminals by means of a sliding contact. There are 3 states, Off-Disconnected, On-Disconnected, and BGA-Connected with Auto, whereby the device will disconnect when it senses low battery, and reconnect when it senses charging. Cycling the switch Off & On will also reconnect the relay. The Battery Guardian Auto remains in the On or Off state, without coil power.

Note:

The BG AutoSelect 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.
