I have built one of these before and didn’t have much trouble at all. This one has me stumped. I have reflowed everything. Is there anything obvious that I am missing. What should be my next step? I have a multimeter but have never used it for trouble shooting. Thanks in advance! -Jason
I have also double checked all of the components against the build docs.
Hard to tell from the pics but it looks from this one angle that you may have the white and black wires mixed up.
See image to the Tip Pad. The white arrow should be the white wire and black arrow should be black wire.
T stands for TIP and routes from Main Board T to the 3pdt and ultimately to the jack TIP lug.
Thanks for your help! On the out side shouldn’t the arrows be reversed? My input side is white on top and black on the bottom and my out side is black on top and white on the bottom. I did this based on the wiring guide with the purple wires where I have used white. I forgot to note that it passes signal when bypassed but when on the LED is lit but no sound passes.
The white “audio” wires both go to the top T Pad In and Out as shown. The other Pad uses the black wire is ground.
You can verify this using your DMM in “continuity” (beep) mode. You can also verify the audio path
The purple wires in the document also both go to the top T pad as well.
Your white audio wires need to both be connected to the T pad. Then to Lugs 1 and 7 of the 3PDT then from Lugs 2 and 8 to the Jack Tips respectively. It is the same numbering whether using a 3PDT Board or not. This again can also be verified with your DMM by a Beep when they are connected properly.
Here’s a PDF for continuity testing

Select the continuity function put your black probe in the meter COM socket and red in the ohms resistance socket if its an auto ranging meter select the ohms function and press the range button to select continuity mode
Once selected touch your 2 probes together and it should beep confirming it’s in continuity mode
Thanks so much! That was totally my goof. I was looking at this diagram where the Out T Pad is reversed but I was only looking at the color of the wires not the T. It took a while of just staring at the wiring diagram and then going to the 4 track build doc and staring at that for a while to figure it out. Super quick fix! Thanks so much for your help! -Jason
