Hello!
I have a carputer in my car, and when I turn the ignition OFF, it stays on for about a minute, then hibernates. I have measured the current draw after ignition off, and it is draining my car. What I would like to do is to make a 12v delayed relay so the computer has power for 2 minutes after ignition off, and then cuts the main power. I was thinkin a capacitor and some other stuff, but I really don't have a clue. I would believe the relay's coil is about 120 - 150 ohm. Any help with this?
