Almost all LED buttons need to be connected with the correct polarity to work.

Test the LEDs before you install them to be sure all the LED holders (red part, front center) are oriented the same way in the socket. (black part, right side)



If the LED doesn't light up, unplug the LED holder, turn it 180 degrees, and plug it back in.   :cheers:

I usually orient the LED holders so the negative lead connects on the same side as the large black plastic tab on the socket. (black tab goes with black ground wire ;D)

I'm sure I'll be doing this a few times!  I just wasn't sure if there was a way to determine which was positive and negative on the led piece (red in the middle) without just plugging it in and testing it.  Usually there is a long and short wire, when its all in-cased and wrapped up, its hard to tell.

Good suggestion

DaOld Man:

If you have a digital multi meter with a diode checker, you can use that to determine the led polarity.
Touch meters probes to the led terminals, if it lights (may be very dim) then the red probe is on the positive terminal, black probe on the ground terminal. If it doesn't light, swap the probes.
Also, you will show a voltage drop on the meter, if it is connected correctly to the led.

In case anyone reads this later...

On further inspection of the LED and its casing, if you look at the LED casing and the wires wrapped around the terminals, you can distinctly tell that one is longer than the other and thereby wrapped around more of the LED casing clip than the other.  The longer is your power, shorter wires to the WIZ.

#4: If you use an inline fuse it will go on the yellow wire (if you are using 12 VDC), or the red one (If you are using 5VDC).
It will wire between the power supply and the led wiz...

Sorry for the thread resurrection, but this is said in a bunch of threads and it's not right. The Ledwiz provides a ground path for the circuits it controls. To properly protect the ledwiz, you need to have a good ground shared with the controlled items' power supply and 400ma fuses on each of the active ports.

The "power bank" connections only provide a protection diode for feedback from the coils of relays, contactors, knockers..etc

How does fusing the power supply to the ledwiz protect anything? The 5VDC from USB is limited to about 500ma IIRC before the computer cuts it off. In fact, I've decided to forgo protecting the ledwiz completely. I just hope the coils on my relay boards never short out. BTW, I'm using ledwiz for force feedback and 5 RGB flashers in my galaxy cabinet.
