Hey , Iam trying to find a wiring diagraham for a chinese lasers power supply . Its a LA-d 532-300 (lion laser). Its working fine but have sent it to sydney to my old man , to look at as the fan on the back of the head is coming on start up but then turns off . Tha thermistor is ok as is the pelter . This is the first little laser my old man has worked on a little laser ( normally works on carbon dioxide and xenon pumped surgical yags ). He thinks it is a adjustment that is required for the fan set point .Any help would be greatly appreciated. Its been sitting there for about 2 months and I am keen to get it back .
