Issue with Nano V4

[thrgk]

Hi everyone,

I am trying to wire a NBv4 using a tcss tri cree xpe2 rgb led. I am only using the G and b dies of the led. However, when I pull the kill key a little lights leaks out of the green led even before I turn it on. I replaced the 3 legged transistor, tried new led, recharge port, but still no luck. The cell is charged and protected.

Anyone have any ideas?

That sounds like a short to me. Or a broken/unstable connection.

short on the LED Star. If your green isn't hooked up, it shouldn't blink or anything. It should be dead. Its getting juice somewhere? Stray solder?

That happened to my saber at one point, the issue was the resistor broke off the wire I had it solder to.

it could be stray solder, I checked but I didn't see any but i have bad eyes as it is lol.

I attached a back picture as well, does the arrow area seem to be the issue maybe? I tried to clean it up best I could.

No, that mosfet tail touches that pad via a trace. I think its in your LED star, since you didn't wire the green. Something is amok on the star itself. If you didn't wire your green, how is it even getting power?

Yeah, the wire coming out of here (L3) if not going to a PEX is a problem. Where is this white or yellow wire going?
