Power plug for Gamefield xD touchscreen

[sccarlso]

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!
