Thank you for your help on the previous occasion.
The circuit digram of the watering systom that I have posted I have built
In the power supply section the +and- 6 Volts is working ok.
The voltage at the 3 Volts DC pins is only 2.5Volts and with load the volts ar
2.5 .
I have replaced the zener diod wich is 3.6V 1W .
I also replaced the R1 200 to 2K2 Resistor.It was smoking.
Where is the problem as the zener should only allow 3.6V
I have to maintain 3V
