So I'm wiring up my footswitch to a DIY pedal kit.
The circuit was working fine when tested with a battery clip and wired straight to the jack in and out sockets. I commenced wiring the footswitch and 9v and LED. the led works fine. the pedal works in bypass when "off" i.e. north plus common. but not when "on" - I get no signal. no ground buzz. no hissing.
So I poked around the switch lugs with my multimeter and find the following weird result when the switch is "on" i.e. south plus common
NORTH: 1 2 3
DMM reading north & common: OL OL 0.300 @2M settings on DMM
COMMON: 4 5 6
DMM reading south & common: 0.0 0.0 0.0
SOUTH: 7 8 9
surely I should be getting an OL reading between 3&6 if the switch is connecting south to common?
Is my switch buggered?

yes - the switch is wired in full - but no 9v power running through it.
I checked/traced continuity from input jack to switch in to switch out to board. the same on output. checked my grounds. everything.
the circuit was working before the switch was wired....be jiggered if I know! and it works on bypass.
it's a fuzz dog kit with his suggested true bypass switch wiring if that helps anyone?
I'd been right through the pcb and reflowed/removed and resoldered every joint prior to testing AOK with battery before moving on to the switch.
just thought that - i'll de solder lug 3 and 6 and measure with the DMM before resoldering and rechecking. if I get the same result would that indicate a pooped switch?
on my battery test the PCB and battery were not in the enclosure.

was hoping to put a picture up of my switch wiring but failed miserably.
it is a fuzzdog pedal parts kit and his switch wiring diagrams are on everyone of his kit build instruction PDF's.
