SOLVED Pathogen build, no audio, no led

[paulbarrette]

Hi
I have a pathogen build with a 3 pdt stomp with a mini pcb board

Pass thru works ok
Stomp engaged, no led, no output

Pcb + to mini pcb IN shows-9.29v

I suspect the 3pdt but it is unclear what the proper set up is. Not sure what to look for in the switch.

Attaching a pic

Appreciate any advice.

Its hard to tell but I think your in and ground wires might need to be swapped.

Edit, actually I take that back. I think the alternating colors threw me.

Here is a clear pic. The yellow and green is a bit confusing

Lol I think it put me in a trance or something. I would try testing continuity at the wires for the gnd and switch. You should have continuity with the effect switched on. If not I would try reflowing the middle lug as it looks like it could be a little shy on solder. In general on the tabs on the switch you should have continuity from the middle row to the top row tabs one way and the middle to the bottom the other.


But you will also have continuity between pins 1 and 6 and 3 and 9 as they are connected on the breakout board.

I verified that there is continuity between middle and bottom then switch on middle and top.

Note. I am testing with the multimeter buzzer between the lugs just to be clear. I guess this rules out the switch

I think the switch is probably good then. I would check at the wires for ground and switch too just to make sure it is going through the joint. Otherwise I would start tracing the power from the inlet to the LED. Go black to ground and then start with red at the DC input. It's possible the wires to the power supply are backwards. Some of the DC plugs have a bypass connector that only has continuity with the switch unplugged also.

Have you checked your voltages yet?

Btw i suspect my power wiring reversed if i am getting -9.29v as opposed to positive 9.29

That’s what I was curious about.

Let’s see your wiring for that. If anything, you should get the led to light up.

Confirmed. Fixed the polarity and the led lights up!

Thanks guys. All working now!
