Boss SD-2 wiring

[enquiryband]

does anyone know how the boss sd-2 is supposed to be wired up? i got one with no inputs, outputs, on off switches, and no battery jack. if anyone could give me a hint as to where this stuff goes please help me out.

First, see if you can find an SD-2 schematic, and post a link to it here.

alright thanks. that would be very helpful. i spent at least 6 hours on it yesterday trying different combinations and nothing seems to work. all i get is a high pitched whine.
anyways, here's the schematic i found.

okay, so i found one of the three jacks. dont know which one it goes to but it has a grey cord with a white one in the center. the other two are being pulled from a scrap pedal.

Yo, here's another one from the gallery, with an image of the board as well... it's a bit blurry, but it should help:

Do you still need to know where the cables go? Because that picture in the last post is actually all you need. Now it must be very easy.

all but the effect on/off. where does the other end go? if i hook another on/on switch connecting the remote, how would i hook that up?

thanks everyone!

The on/off switch has only 2 connectors.
The wires in Boss pedals are numberd (did you know that?), so one goes to the mainboard numbered as 2. And the other one goes to ground.

Is this helpfull?

i got power to it but it doesnt shut off when i unplug it. i hooked the on off switch to i think 2 and 3 while 4 and 5 are the battery connections. the red (crunch?) works and i think the green (lead?) would work if i got a new switch since the current switch is broken off in the green channel.

According to the schematic 3 and 4 are the battery connections. The on/off switch is connector 2 and ground. Just follow the schematic and you can't go wrong there.
