The pump does not work and may be stuck only with the white appearing corrosion that is so evident through all the 1/2" tubes rather than the pump be broken. I have left the pump connected to the reservoir and filled the reservoir with water and given the two a shake and have left them that way for 3 months and soon I will try to start the pump hoping it will work. The last time I tried to start the system with the pump connected to a motherboard the kit siren went and the water did not move around the system. This is the kit I am posting about and is not "my kit" but my kit is complete but not working like I said. This is the pump showing the connector to the reservoir where the Gigabyte auto cut off mechanism has its ciruit board housed...in the bottom of the reservoir. I had to make the 6 pin connector because the guy I bought the kit from cut the wires and the connector off so I had to make the 6 pin connector and rewire it and the motherboard pin socket and the rest of it.... I am still hoping I connected the wires correctly. This is the 6 pin connector I made...the bottom picture shows the end of the connector which has the 6 sockets for the 6 pins but the webcamera does not a very good picture make. ...also I think you will not see the wiring in detail to see if I wired it correctly. I did spend some time thinking where to put each wire and I "think" I have that right. When I tried out the watercooling system the siren went and the LEDs lit up so I suppose I got something right. ...btw, I do not drink alcohol, the tankard is a great coffee cup. I wanted to ask how to clean the insides of the pump hoping the reason the pump did not work is the corrosionout but I have found a thread about using lemon juice in water and there is a lemon tree here so...has anyone some advice as to how much lemon to use and how to approach the flushing of the pump?
