Default Blue 1300mW Laserpointer Repair [NEED HELP]

Hello,

I urgently need help with my laserpointer. Yesterday I accidently broke my 1.3W blue spartan laser. The problem is that I have pulled the two power cables. Now there is no connection between diode and battery pack. I don't know which cable i should solder to which leg of the diode. I uploaded some pictures of the issue too.
Please, I really need help. The laser is vey important for me.





Many thanks in advance.

Looks like you are lucky that the pins on the diode survived.
So advice number 1. Don't turn it on. Some drivers die instantly when turned on without load.
Then you have several options:
1) wait for someone who has spartan. There is a chance the colors are same for all spartans.
2) Build test load (search around here how it is done). With that you can safely turn the laser on, and use multimeter to find which wire is positive.
3) Dismantle it a bit more, make pictures of the driver (preferably better ones than these) .. then there will be more information to build on ..

Probably the black wire is the negative and the purple the positive but i think you should do what DrSid said ! Make a testload and check it ! I dont know for the diode but i think that the pin that is closer to the red marking is the positive and the pin that is closer to the black is the negative ! If i was you i would e-mail dragon lasers and ask them !

That is not a Spartan. It's a Cree C6.

You should ask whoever you bought it from. If you can't do that then probe the host and the two wires for continuity, that should tell you which wire is what if you are lucky.

Finally, Pontiacg5, somebody noticed that CNI does not use aluminium heatsinks with set screwed Aixiz modules and Aixiz focus rings on top.

Darthxbox, if the laser is very important to you, maybe you should've taken some care of it not to drop it or whatever it is you did?

Lesson learned the hard way is the lesson learned the best way, I say.

It's impossible to determine the output of the driver inside based solely on the wire colors. While I always use black and red wires in my projects accordingly, not a lot of people I've met do.

Where did you buy that laser? Perhaps a person will be kind enough to repair it for you for a fee (don't think about getting it free, you'll be lucky if they agree to repair it at all).

If not, one of us can take a look at it.
