Yes when the green led does not work, Q3-pin 3 does not go high.Hello,
When the green led does not work, Q3-pin3 does not go high.
Q3 gets triggered by Q2-pin3.
Does the led on Q2-pin3 change state?
Shorting Pin 1 and 2 of Q3 had no effect tried a few times and got the timer started again ???Hello,
What happens when you short Pin1 and Pin2 of Q3 for a short moment?
Check the connections of C7 and R11.
Those components should trigger Q3.
Sorry Bernard tried this 100 times and changed all loose wires to rigid ones and now works a treat but still no repeat functionThe repeat function should already be in place. On 3C check connections from Q3-3, C2, R6,,& D2.
Done this and works as you said. It even resets back to red, and starts all over. But when I reconnect as normal, nothingMy feeling is that Q3-3 on reset is not going to hard ground. To test you could lift Green LED & R to +6, cathode to Q3-3. Green should then always be on except for last 4 sec.
If Green does not come on, replace Q3.
