Hi, my circuit is working when is of the bike and when I put it on, there is weird behaviour. It's giving signal properly for 3s~20s. Then output of hall effect stays high, even when magnet is close to it. I'm using not gate, because hall effect which I'm using has sinking putput. Hall effect is 55100-3H-02-A. I tried even pnp style ignition, but it had same problem. For power I'm using L7805c and L7812c linear regulation. When I unplugg ignition coil it's working properly.
