Hello,
I would like to build a timed circuit that will provide -12V to an actuator when the key is removed from my car ignition.
When the key is turned to ACC on the car, I can get a constant 12V, but when I remove the key, I need to know if I can either purchase or make a circuit which will reverse the polarity to
-12V for about 5 seconds and then shutoff.
Any ideas?
