I Connect 9 Vdc on point - and + right side.
When I connect GRN point to 1 point noting happens + not the led
When I connect GRN point to 3 point noting happens + not the led
When I connect GRN point to 2 point The relay works but not the led
When I connect GRN point to 4 point The relay works but not the led

When I connect + VDC tot point 1: nothing happens.
When I connect + VDC tot point 2: nothing happens.
When I connect + VDC tot point 3: nothing happens.
When I connect + VDC tot point 4: nothing happens.

What is the problem?

For best results, make sure R5…R8 are 820 ohm or 1K ohm.

I have change R5 - R8 with R 820 Ohm.
Now The relay works but not the leds, when I make the connection:
GND - 1, GND - 2, GND - 3, GND - 4.

What is the problem?

Hello,

Is there a short across the LEDs?
This would allow the relay to work but not the LED.

5

What do you mean: 'a short across the Leds? '?

6

A solder bridge across the leads of the LED.

Hello,

The problem is resolved. The 4 LED are bad and I have buy 4 new leds. And Leds and relay works.

Thank you.
