ABSTRACT:
A battery protector/automatic ON switching device comprises a first terminal for connecting to the generator output of the vehicle and a second terminal for connecting to the input pole of the vehicle battery, and a diode serially connecting the first and second terminals to permit a charging current to flow to the battery and block current flow in the reverse direction. A third terminal for connection to a load circuit of the vehicle connects to the first terminal through an automatic switch which will switch on the ON condition only when at least a threshold voltage sufficient to excite the genertor to its full output is experienced at the first terminal. The first terminal connects directly to a dummy pole that may be gripped by a booster cable for providing a booster charge to another battery. The diode prevents current flow from the battery of the source vehicle and the inadvertent damage thereof.
