Thread: Wiring Help - power on without Kill Key NB4-graflex build

  1. #1

    Question Wiring Help - power on without Kill Key NB4-graflex build

    Newb alert: First time build - power on with/without kill key
    I have graflex with NB4, 5mm crystal led and 3mm led (power on), main B/B/W leds, goth3d knight chassis
    I know I wired incorrectly somewhere and I think it's at the recharge port. Alternatively somewhere on the NB4 solder joints? The main LED and negative power solder joints are very, very close to each other. I thought for sure I soldered correctly and I've traced as much as possible but obviously I have a power short somewhere.
    The symptoms are with/without kill key:
    - 3mm LED power is ON with/without kill key
    - activation switch turns out main leds and sounds with/without kill key
    Just trying to troubleshoot before I wreck havoc on the build and myself. I'm a little concern I will fry the NB without knowing where the problem is. Any help on where to begin would help. Be gentle...I'm almost retired.

    You would need to post clear pictures of your wiring so we can see what's going on.

    Problem solved. I had the tiny, tiny amt. of solder that rolled behind one of the negative terminals of the recharge port effectively bypassing the kill key. Removed it and all is functioning.
