12v Countdown timer, runs a fan for up to 72 hours, resets when Acc supplied.
Hello Circuit Experts!
I am trying to run a small 50mm 12v fan while my car is running, and continues to run from the car battery for up to 72 hours max after I switch off the car. The timer would reset when I start the car again and not start counting down until the car is switched off.
I think this could do it, but I'd like to delay turning off, not turning on?

But if it doesn't I'd be capable of soldering it myself, if given a circuit diagram.
Thankyou very much!
