7091 not working

[scott11]

I just purchased a used 6000 with a 7091. The 6000 works , and the leds on the 7091 work, they show switching between the 2 powers, and they show the pump on and off light, but whatever I do on the controller has no affect on pump output.

This is my first tunze product so any help would be great.

Thanks

I noticed the wire going into the 7091 was loose, so I opened it up. Turn out only the red and blue wire are connected to the board. There is a black, green, and white wire, all just hanging there. If I could get instruction on where to connect the wires I think I could repair it.

Anyone have a schematic?

The white wire is the only other one that should be connected, only three wires are used. You should see a third solder point next to the other two wires that has nothing connected or a few copper strands that broke off, that is where it connects.

i see the third solder point. It seems like the black wire is much longer than the white and green. It almost seems as if the black was connected.

I will try to attach the white and see if it works.

Thanks for the help.

Then it is probably the black, The wiring changed over the years, for example the current is orange, blue and white. The three longer unclipped wires would be the connected ones.

I attached the black, and it is now working. Thank you!
