12V Timer Circuit Activated By Power ON

Several people/subscribers have requested this circuit. If you are looking for a circuit for your vehicle that once 12v power is supplied to the circuit, a buzzer or another circuit is activated for several seconds then turns back off, even though 12V power is still being supplied, then this is the circuit you want. I found this circuit online, but made some modifications. The circuit came from a VERY reliable source(Talking Electronics).
