Did I wire this right?

Hi All,

I'm finishing up R.G.'s Omni Drive and am substituting DPDT switches for the SPDT switches so I can have the pretty lights....

I just tried the system and distortion is working (have not wired up octave or filter yet, just bypassing for now) but I have boost, scoop and mode in place.  Doesn't seem to be much difference in sound when I activate scoop and boost, so I'm wondering if I wired the switches up right.

Here is how the SPDT's are wired in the original diagram:



Please note that some switches do not use pole 1 at the top.

Here is my "conversion":



After some research I'm assuming I wire 1,3,5 as 1,2,3 are on the SPDT and 4 and 6 to the LED.  I crossed the grounds and connect the LED (with resistor) to pole 4 on the DPDT.   Is that correct?  Do I need to do anything with pole 2 on the SPDT's that use Pole 1?

Thanks in advance!

Without trying to dig up any schematics for the omni drive, I can tell you that it all depends on the original wiring. There's a couple of small mistakes - with the switch in the lower position, 4 connects to 6 (your numbering). If both those lines go to the led, youre shorting it out. This is a way of shutting a LED off but will eat a lot of power and heat up a battery nice and quick. Also, where do you get power from?

That said: it's more common to number a DPDT like this
1 4
2 5
3 6

123 is a switch with 2 alternating between 1 and 3, 456 has 5 alternating betweeen 4 and 6.

a DPDT is the same as TWO SPDT in one box, latching at the same time.
So, if you want a LED when 2 is connected to 3, connect V+ to resistor to LED+, LED- to switch terminal 5 (the middle one, note the new numbering) and connect 6 to ground. Leave the other switch alone unless you're sure it's possible to use connections from that side.
If you want a LED when it's the other way, connect ground to 3.

Hey, if you want a green LED in one position, and a red in the other, connect the ground to the middle lug (5) and run two LED-lines, one connected to 4, one to 6.
Does that help?

Yep, tremendously.  Thank you!
