Abstract

The present invention relates to a power source with an anti-reverse connection and short circuit protection circuit for starting motor vehicles comprising a rechargeable battery, a flash light circuit, a positive battery clamp, a negative battery clamp and a circuit which comprises two relays and at least two diodes; one terminal of each relay is connected to the positive battery clamp; the other terminal of the first relay is connected to the positive terminal of the first diode and the negative terminal of the first diode is connected to the negative battery clamp; the other terminal of the second relay is connected to the negative terminal of the second diode and the positive terminal of the second diode is connected to the negative battery clamp. The power source provides an effective circuit protecting against reverse polarity connection and short circuit of the battery clamps.
