Sorry
I know this has been gone over many times
and I done searches and read a few of posts
cant seem to wrap my head around this simple concept
but for some reason my LED comes on when OD is off opposite of what I would like...OD-on LED-on simple right....
tried wiring few different ways (tried the brown note way, heisthl's way)but nada
using the Marshall 3 button replacement (AES) and jborders5 relay boards with Omron G5V-2-H1 relays
any suggestions are appreciated
Whichever switch position allowing the led cathode to ground gives led juice to turn on. Think you need to swap terminals somewhere on your footswitch.
Take out the 1K resistors and wire the LED in parallel, and rewire the AES FSW like this pic using 150R resistors. Green goes to pin 4, red white yellow to pins 1,2 & 3. Pin 4 goes to ground from the chassis jack.

Thanks Tom
started with that layout but no go...OD on no LED OD off LED on
This has to be a simple fix
I must be tired from the Holidays or something.
Like to finish this up and get it in a cab and move on to next build
bummer when the little things bother me so much...
few more pics of the relays and switches if anyone can take a look

I already installed a 5 pin din (MIDI) and made a cable with MIDI connectors
not sure this wiring will work with that?
but I will give it a try
thanks again

Not really following the photos, but may I suggest the wires to the OD relay's NO and NC terminals be reversed?
thats a good idea could that cause my issue?
I've been kinda lost trying to figure out which way to wire the relays
I could easily be way off with my wiring
not really sure how to check
Bear in mind your relays should have the supply voltage on them all the time, and what the footswitch does is supply ground. The Marshall replacement footswitches ground the relay by shorting across the LED. so the LED cannot light when the relay is activated and the LED only lights when the relay has no ground (i.e. not activated). If you want the LED to light when the relay is activated you have to let current flow through the LED by installing the LED in the path from ground to the relay.
Thanks for the explanation heisthl
I think I understand...it seems understanding and putting the wiring into place is where my lack of experience really shows. I will look at your
wiring schem some more...this is one I have
I assume I would want the right side pic?
Just to clarify...I would run the 150 ohm(I have 470ohm) between the 2 legs of the LED
and the wire from the 5 pin jack is on the far right?

I suggested it because it seems (because I'm not the one who has to do it) a simple thing to try.

Yes the far right wire goes to the jack pin that continues on to the relay - also the ground symbol represents a wire from the jack too, which goes to all footswitches in your pedal and comes from the same ground as your relay supply..
Thanks heisthl
also does the B+ or orange lead in my first pic connect to the center lug
on all switches in pedal?
Also as suggested by DonMoose
can my relay wiring be wrong and cause this?
thanks for your time
