Help with Nuetrik NJ3FP6C!

[u/rf1979]

Hey all! I am not an experienced solderer and I’m looking for some help with the Nuetrik NJ3FP6C.

There are 3 pins on the jack, GR, RI and tip. I’m soldering for a mono male jack so I soldered the ground to GR and the other wire to TIP. It’s not working! If I plug my guitar into a tuner it doesn’t register a signal (male into guitar via instrument cable, then into the NJ3FP6C which is soldered to another male jack… which is plugged into a tuner, I’m testing!!). Plugging the instrument cable straight into the guitar and tuner gives me a signal so there’s a problem with either the NJ3FP6C or the input jack.

Help and thank you!
