I have a koi pond that moves the water with a Hayward Super 2 pump and a 2 hp. A.O.Smith 220v motor. I replaced the T104 timer, which I wired to be lowspeed/ high speed mode instead of on/off, as the Koi need constant water flow. Problem is this: I disconnected the wiring thinking it was a wiring problem but forgot how I wired it in the first place (4 years ago). I have a red, black, white and green from supply and a black (common) a blue (low) and orange (high) to motor. Any ideas?

Black to black
Red to blue or orange depending on speed
White - capped
Green - ground

This assumes that the high/low is speed and not voltage. The black and red input can be interchanged.

A.O.Smith Electrical Products Company (http://www.aosmithmotors.com) should be helpful, if you want to check with them.

Thanks, K.I.S.S. but I am concerned about hooking it up to a T104 timer (I,e. a 1 2 3 4). I do remember that 2 (load) and 3 (line) had a jumper between the two, and all the white wires went to "A" ( I also have a light and a GFI outlet running off the timer). Thanks again for taking the time to answer the questioin.

Does this help any? http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t104%20-%20english.ashx

The white from the wall goes to terminal A and probably all the others.

Cn you figure out the rest?

Here is the problem. I have 3 wires coming out of the motor; the low speed wire and the high speed wire I can figure out, but where does the common wire connect to? Is it always hot or considered a nuetral wire? The T104 diagram only shows 2 load wires.

The common is considered another load wire. When you are using 240, you have to break both legs with a switch. Each leg is 120 V with respect to Neutral.

It's customary to call the connection a 4 wire 240/120 volt with L1, L2, N and G. L1 & L2 are interchangeable.

Thank you. You have been very helpful. I think I know whaty to do now.
