Anyone haveing probs with the relay delay circuit
I build the circuit here just as listed. It worked for about a month and then i started haveing probs with it. I replaced the relay and then it worked again for a few days. Now heres what its doinging. Its not killing the power at all. And i cant figure out for the life of me how in the hell the relay is getting power. Ive shorted the cap and everything to try to get it to turn off but no such luck. Im wondering if it could be a heat related prob affecting the beta of the transistor. Anyone haveing similar probs.
