SOLVED Seahorse LED

Hi, I've finished building the seahorse and it is working fine and sounding great, except the LED won't light up. I have tried 3 different LEDs and wiring the led both to the PCB and to the footswitch like I normally do and nothing works. I believe the led is suppose to pulse in time with the rate setting, and the build docs specify a 3mm red led as "D1" but D1 isn't on the layout diagram so I assume it just goes in the normal led spot? A bit confusing as the build docs are pretty vague and the original eqd pedal has 2 LEDs. Any help would be much appreciated, thanks
 
the LED should go in the A and K holes on the PCB the ground and SW wire go to the 3pdt footswitch as shown in the diagram for the seahorse build documents. you need to figure out how that diagram will work with the extra board you are using on your 3pdt switch
 
Hi, the led is in the a and k holes and the ground and sw go to the ground and sw on the footswitch PCB. The pedal is all working great and turning on and off with the footswitch so everything must be wired up correctly.
 
Hi, I decided to just get rid of the footswitch PCB and wired it as per the build docs and it's now working, thanks for the help. Don't understand why the footswitch PCB would affect the led on the main PCB but obviously it does for some reason :confused:
 
The Seahorse uses one LED to show both the rate and when the pedal is in or out of the music path. So the footswitch has to also turn the LED on and off, and when it is on it also shows you the rate of the pulsing. That is why the footswitch is a part of the circuit for that LED.

You are using a small pcb on your footswitch that was also designed to hold an LED and you need to have some way to complete that circuit even though you want to use the LED on your main PCB. Otherwise your LED on the PCB will not work because of that open connection where the LED on the footswitch goes. That is why I suggested putting a jumper on spots for the LED on your footswitch. You could also leave your board the way it is wired now and just put an LED on your footswitch if you wanted a separate LED to show when the pedal was in or out of your music path.

You can use any size LED you want for your pedal.
 
Thanks, all sorted now. Didn't think the led size would matter, I only asked about is as it specified a 3mm in the build docs, which I haven't seen in any of the other pedalpcb build docs I've looked at.
