Hi to everybody. My name is marco and I am a new entry in this forum. I am from Italy and I am a proud owner of a old but glorious STL 11000. Now it happened that its original power supply just stopped working (died) and I tried to replace it with a standard new one 12V-10A but I think I did something wrong because the Camera works perfectly but the cooling doesn't work at all. Basically I connected the pin 1,5,6 to the +12V and the 2,3,4 to the "common". The camera works fine as well as the filter holder but sensor temperature doesn't move and doesn't go down. I think either the Peltier is broken or something in the new power supply is wrong (pin connection or pin signals etc..). Is the original power supply a specific power supply and I should replace the old one with a new one, if it still exists? Any help would be very appreciated. Thank you Clear Skyes Marco
