5 WAY TRUE BYPASS PEDAL?

[Kentone]

Ok, I have this true bypass pedal ive been working on for the past week and Im having alittle problem. I have wired it the same way as the single bypass pedal and just did a jumper from the output pole to the input pole  to connect the switches together. There is a Tuner mute in there as well that connects first from the input.

My problem is that when I plug power into the 5 way bypass pedal and the I get another pedal to plug into one of the loops and plug power into that fx pedal it shuts my whole pedal board power off. Whats going on here?

It sounds like the you have the polarity reversed on the Bypass strip.

Or the pedal could be positive ground.

[Kentone]

I dont think the positive ground is the problem. all my pedals are negative grounding.

What do you mean by the polarity being reversed?

Why does it require power if it's just a hard wired true bypass box?

Regardless, you must be shorting out the power supplys. Double check your polarity and grounding.

yeah, but what about your wallwarts?

[Kentone]

explain please polarity & wall-warts.....

[smoguzbenjamin]

You could have connected the wallwarts input's (poles) the wrong way round, creating -9v instead of +9v. If you give your effects upside-down voltage they're not going to like it.

Does the bypass pedal work if you remove the DC plug from it?

[Kentone]

I switched the fx input/out pole wires on the switches an its doing the same thing.

The bypass pedal does work perfect when there's no power. The bypass pedal works if you plug the bypass pedal in to power but as soon as you plug a different pedal into one of the bypass loops and plug in power to the fx pedal, it shuts everything off.

But everything works fine when there are no FX pedals plugged into one of the bypass pedals loops. LED's and the whole pedal board works fine. its only when you occupy one of the bypass loops.

[Khas Evets]

It appears that your signal is passing properly, but the LED indicator is causing problems. So... Is the DC jack wired center negative? Is that connected to the chassis/grounds? Is the positive lead switched by the 3PDT switches? It sounds like these are reversed.

Does it work if you have a pedal connected running on batteries?

How are the FX send/return jacks wired? What type are they (mono/ stereo, switched when plugged in)?

Is there a diagram you're using that we can look at?

[dosmun]

What type of DC jack are you using on the Bypass box?  Make sure that the + is not connected to the chassis.

I found this in the FAQ page, so I'm starting over with this drawing.

With all the grounds going everywhere on this drawing, would I be able to use a main ground buss instead of running all the wires which will come cause there are 5 switches. Or do I need to run the individually???

provided all the grounds are wired together you can use conductive elephants to connect them all if you wish.  

A word from the wise; you have to break eggs to make omlettes.

Just go for it dude! Blow some stuff up, make some mistakes, build piles of useless circuits, it's the best way to learn. Learn from your mistakes! Who knows, you might even come up with a far better way of doing something!

If the byupass strip is working fine down't mess with it.  The problem is the LED power only.  Just make sure that the LED power on the Bypass box is negative ground and that it is isolated from the Bypass box.
