so it has a consant 12v input going through it, and when it recieves another 12v 'control', it allows the original constant 12v to continue through for a specific length of time, based on the setting of the pot. Once the timer expires, the 12v 'feed-through' is cut.
Am I understanding this correctly?
If so, what do you want to happen once the timer has expired, and 12v 'feed-through' has been cut?
The state of the circuit at that point is, you have a constant 12v going into the circuit, but not being passed through. You have a 12v 'control' voltage set to TRUE, your pot is set to the preveous setting, and the timer is expired.
