ok, so the people at the other board seem to have stopped helping me, and i'm a little stumped here.
I attached the diagram I used with pin numbers and part numbers.
The first half of the circuit works fine, the vRef, it generates a varying voltage from 0 - 60mV when I turn the pot.
Nothing else works after that, the relay is getting nothing but 4.95v that doesn't change no matter where I turn the pot and the relay never gets activated.
So i dont know if i connected something to the wrong pin on this particular op amp but maybe someone here can help cause I really need to get it done my car has been apart long enough.
