I recently got a laser from survival lasers (1.4 watt blue kit) And a diode from dtr. And i put it togeather following the instructions EXACTLY! I cut the diode wires to 1&1/2" and soldered them to the driver wires.I'm not the BEST at soldering but i got them stuck togeather. :crackup: I did have ONE tiny little problem... When i was soldering the negative wires togeather the heatshrink tubing "shrunk" to the driver wire so not wanting to cut the whole thing off i used electrical tape,and after seeing the laser didnt work i took it off... Still didnt work... Did the electrical tape somehow poop on the whole laser?! :wtf: And yes i put the batteries in the right way. (negative towards the tail cap) And no i didnt let the wires spin when i put on the crown. (top) So what are some reasons my laser isnt working? Because i'm completely stumped right now.
