earlier tonight i just received my (first) new Tunze 6105. I was all fired up to get it set up and installed but it's not working. I tried each of the 3 jumpers, the red light on the power supply lit up on the 12 and 18v just fine until i got to the 24v. With the 24v in, the light and the prop slightly pulsed never making a full rotation. I took the cover off and checked the shaft and everything seemed to be in working order. Only thing i noticed at all was when i had the cover off, i tried adjusting the red power knob (again testing with all 3 jumpers) and i'd see the propeller slightly "flinch", the best way i could describe it. It maybe flickered a 5th of a turn and then sprung back to it's original position. Never could get it to run at all. I also noticed that when i plugged this into every GFCI outlet in my home there was a slight spark when the plug touched the outlet. None of the other equipment on my tank did this. Home is less than 5 yrs old and never had any electrical issues at all. Not sure at this point if i just need to return it to the online vendor i got it from. I have to say, i ordered this to run along side my MP40 before i decide which way i want to go in my 225g tank and this is rather disheartening for a brand new piece of equipment. any help is greatly appreciated!
