So I switched my boards back on the heat sinks as I had them mixed with 4K/3k and now only a single board will work at a time. I’ve tried every configuration possible but they both won’t fire at once for some reason?

any thoughts as to why?

Snob · May 17, 2020

are you wiring it up the same way it was before? is the wire your using between the 2 boards fresh? Maybe they are bad wires?

Can a solid copper wire go bad? lol

Voltage maybe different between these boards I dunno. just an ideal bad wires seems more plausible.

TreeFarmerCharlie · May 17, 2020

Maybe one of the wire terminals on one of the boards isn’t making a connection? When it doubt, pull out the voltage and ohm meter.

Solid wires tend to break more often than stranded. Sounds like a connection issue somewhere.

Like Charlie mentioned, check resistance

iPerculate · May 17, 2020

Are you intending to do a series connection? That wiring looks like parallel.

As you can see by the pics I have hooked each board up by itself using every connect possible.

No

Never knew this. I’ve tried all 4 pieces of solid wire I have on hand and nothing works.

Yeah, I see that now.

I hooked up the original driver that came with the 4K boards and still nothing.

Airwalker16 · May 17, 2020

It can't be a broken solder joint on a board if each one will illuminate still, so that takes care of that. So it has to be from the wires somehow

But you can get them to light up individually?

I tried every possible configuration before making this post. As seen in the pictures.

Well I guess I’ll head and get some solid core wire

what gauge should I grab.

Nappertunity · May 17, 2020

I'd check the multimeter to trace where the break is. They are always handy to keep around.

Nefrella · May 17, 2020

Honestly I would rewire the whole thing and go from there. If you've already do e that and said so previously, apologies . Good luck, youll get it, just keep plugging

18-22 awg wire

Series:

Series connection is only 1 jumper attached between the boards, not 2. I'm not sure what boards or configuration that you are running that's why I wondered if series or parallel was the goal.

My HLG kits run as series circuits
