What I'm trying to do, is have a short output pulse of 12vdc (possibly around 1A) for about 3 seconds when 12vdc is applied to my circuit, then when power is removed from the circuit, have the same lines reverse polarity.
The output lines can float at any other time.
Obviously, I need a ground, constant power and switched power lines.
This of course could be done manually with a center off DPDT switch... But you know... That's just too low tech.
Any quicky ideas I could start with and build outward from?
Thanks!
