Hello guys. Recently I bought a k40 laser machine. After fitting all the accessories I pushed the on button and blew off the fuse. I checked the tube and it was full of water. I guess it was cracked so i asked for replacement. The seller told me to disconnect and take out the tube,replace the 6A fuse and turn on the machine to check if the psu is ok. I did it and again the fuse blew off. My machine doesnt have a on/off laser button just a central switch. On the psu i see that they have soldered together those two pins for the laser switch. My thoughts are that i cant turn on the machine without the laser connected and the only way is to free those 2 pins(cut Voltage to anode) so i have power only to the motors. All the other wires look ok (attached).I just dont know if it those 2 red wires going to the psu in AC AC need to be checkedfor polarity issues.Any ideas on this?
Thank you in advance
