Problem ONLY When Using 9v Battery

[zozoe]

Good eve' all~ I'm having in issue with this older (but not Uber vintage) Ibanez Tube Screamer, that when I got it used, the pedal did not light up or work with a fresh battery & cables inserted. I checked for positive continuity between the battery holder lugs & their associated connects. But it works just fine when using it in my pedal board, powered by juice from the wall. Once, I was able to get a momentary flicker of light out of it by fiddling w/the wires & battery instered, but I couldn't do it on command & try to trace the culprit. The pedal did come with an intermittent on/off button, but that was easily replaced with the exact same button. Any thoughts, or other not so obvious checkpoints? Many thanks in advance~~ Stay safe & be well!!

That thingy where the battery plugs in

Its loose/bad/broken

The battery aint making contact all the time


Swap it

I screwed up & accidentally knocked the black wire from the on/off switch to wherever it's supposed to go. From my pic, it looks like it goes to some contact on the input, where there are already two blacks,,, one that goes to the output, & the other to the DC & diode lug,,,
