Again, in a jam thanks to suppliers. 🤬
Finally received my 32” Gamefield touchscreen and no power harness! “Oh, yes it comes with the power plug”. Right! $800 for a touchscreen and can’t include a harness or even a $5 matching plug. Ugh
It’s pretty simple. But with no documentation of any kind, I’m just guessing. Hoping someone might have the info.
It’s labeled 24V DC. Easy enough.
There’s a 6 pin AMP connector for the power plug. Uncommon connector. An AMP Mate-n-lock type. Easy to make connectors though.
Problem is there are green wires on pins 1 & 4. And red wires on pins 3 & 6.
Not sure why there would be two 12v circuits to make 24v when one 24v circuit would do?
Red is obviously positive. Green negative. The negative connections are a no brainer.
So would this display have 12v on pins 3 & 6 to make 24v?
Or is it possible there is 24v on both pins 3 & 6, and there are just two 24v circuits? Thus, the quagmire.
I guess I could try 12v on 3 & 6. Won’t blow it up by undervoltage. But definitely can’t put 24v on 3 & 6 unless certain, overvoltage can blow it up.
Any suggestions welcomed! Assuming I’ll pull power from the primary display power cable. But I can meter that to get the right voltage. No internal PSU, just DC from the main PSU, so not much current is needed to drive this display. 👍
Thanks for any info ya’ll might have!

Just in case anyone else has this issue. Identified by obscure schematics of the LED driver board. lol
Pins 1 and 4 - Ground
Pins 3 and 6 - +24v
That gets it running!
