3dpt led location

[nosaj]

I have this Dod Yngwie pedal guy wants a led so he can visually see on or off. I found this block the pedal had a dpdt FS in it now. I have a 3dpt and this post but the guy did not add the LED. Where would I put the led wires?

You have an unused bank of switches.
Find which two of the three are connected when the pedal is 'On'.
Red battery lead-- appropriate V drop resistor-- LED (+) ; Attach this to one terminal .
Black/ Ground and LED (-) to the other terminal.

Middle row is ground correct?

I guess that the green wire is the positive from the DC jack and that the battery negative is switched by the jack to the chassis. That being true I think this is what you need.

Yup.

Works like a charm

Can anyone suggest where hum might be picked and if the LED would cause it. I'll have it again tomorrow. I only experienced hum with my round flourescent light near it. Turned it off and it's gone. It is used with the power pack and a high gain amp.


Thanks,

The schematic you posted seems incomplete. It doesn't show the footswitch. This makes me suspicious about the correctness of what is shown.

Can a 3dpt switch introduce more noise in a circuit, this one seems to have . I'm going back stock just to reverify.

The carling switch has 3 connections purple and grey wires tied together on one lug other 2 wires separated.
rewired stock seems quiet, rewired back to led setup quiet. Noisy input cable. Problem fixed.
