This circuit is intended to cut power to things like auxiliary lighting on a vehicle while the vehicle is off. To prevent draining of the battery.
It was designed for LED strobe lights for emergency vehicles.
Adjustable on off voltages with potentiometer. Change is pproximately 1.6v.
Off @ < 12 volts to save battery
reset @ > 13.6 volts when vehicle is started or battery is changed
Made for use with 5v relays but the actual values of the resistors will vary depending on the relay used.
Not intended for charging batteries...
