hi,Hi Mr Gibbs,
I have found the short the was causing the fuses to blow.I have another problem.the circuit does not reset nor will the beeper stop beeping continiuosly...i have tested it without the ac applied to the relay contacts...the relay is always energized when the i apply supply to the circuit keeping the beeper on.what could be the problem?
You could have blown the 2N2222.
Disconnect R5 from the 4011 output, that goes to the transistor Base, connect the free end of R5 to 0V [ so thats the Base to 0V via R5]
The relay should not energise, if it does, the 2N2222 could be shorted or you have wiring error on the relay coil connections.
Lets know what see.
