S10 laser module wires

Hi, can someone please give me the correct connection for the lase module?

I didn’t take notes before repairing the wires and connector and now I don’t in which order the wires should go in.

I know there is +12V and GND and assuming the 3rd one is laser driver.

It’s labeled on the board as well. 12V - GND - Signal (as oriented in your image). If you switched 12V and Signal, the fan won’t turn on after powering the mainboard (it doesn’t damage anything).

You can find more technical data here: Sculpfun S10 - Diode Laser Wiki and here: Mainboard Replacement - Diode Laser Wiki

Thanks again, I was finally able to fix it… partially… the wires are now correctly in the connector and the fan spins, but there is no laser output. Any tips, what should I check?

For future reference and other users - I measured the direct connections on those pins.

The data pin does not have direct connection to the other header connected directly to the laser (should it?!)
