Help with power injection

[tytygh]

So I'm running 300 pixels (3 strings of 100 nodes) and I'm trying to power inject about midway through since it starts to get dim otherwise. I'm using Wally's Power Distribution Board with three core xConnect pigtails with the recommended power supply.

I detached the data pin from the middle port of my 3-3-3 power injection tee and detached the positive pin from the end male port, as I was instructed to do so here.

However, upon trying it out, just one pixel lit up the proper color as the preceding string (pink,) but the rest are just flickering or unlit. (And again, everything does light up without the tee. It's just not as bright.)

Setup:

Falcon F16v3 ? Extension cable ? Data booster ? 1x100 strand ? Extension cable ? 1x100 strand ? Power injection tee ? 1x100 strand (the one I'm having issues with)

I tried using another data booster, but to no avail. This is my first year, so if anyone could help that'd be appreciated.

You probably already know this, but just in case...

First thing I would check is if the 3-3-3 splitter is wired as you expect.
There is a pin-out for the different ends available on one of the sites (WiredWatts ?).  Verify that the pins are the ones you expect to flow through, and that the one you pulled is the one you wanted to pull.

Ground - and Data + should pass through the T.  The power coming from the string should be interrupted, and the power you are injecting should be added to the new section.  (Note Ground should also be added to the already present ground at this point.)

Keep in mind that though there has been great progress to date, there is no guarantee that the wiring is correct from the manufacturer.  Be warned.

Alright, thank you for your recommendations! I'll look into all of that. Also just realized that the A/C extension cable I'm using for the distribution board does not have a ground port, so I guess I'll try changing that too tomorrow.

Fixed it! It was my extension cable. So if anyone from the future has a similar problem, make sure your AC extension cable has a ground pin!

Glad to hear.
One question, "AC Extension Cable"?  Using for power, or as a data cable?

Alternating Current, AKA these kind

Thanks for the clarification.

FYI - We have had some in the past use power cords (such as you show) WITH POWER ENDS as data/dc power cables.  NOT GOOD!

Now I'm curious as to what on the AC side caused your problem.  Doesn't matter since you are up and running, but still curious.

Most likely that was a band-aid to the real problem which is all the grounds from multiple pieces of hardware need to be common.  You probably got them closer by not using AC cords with the ground lifted but still better to tie the DC grounds together.
