Coming to the rescue of a nephew who thought he knew how to do electric. He purchased and installed a T104 intermatic timer on his newly installed above ground pool to operate the pool pump automatically. Unfortunately the pool pump is 120volt and the T104 is setup for 220 volt. can the internal wiring of the timer be changed to accomodate the 110 volt pool pump by relocating the clock timer wire from #3 terminal to #1 terminal with the other clock timer wire, put the neutral from the panel on #3 terminal and use the terminals 1 and 3 for hot and neutral from the panel and terminals 2 and 4 for the pool pump ? the Clock timer would run off terminal 1 for both leads so the clock would run. trying to find a way to use the timer now that its been installed as it cannot be returned as its already been installed. Thanks

Welcome to TFP.
The T104 clock motor need 220V to run. Without two hot wires from a 220V CB you cannot run the clock motor.
Also, neutrals are never switched. For a 120V circuit you only switch the one hot wire.
Really better to get a T101 mechanism to swap in.

You can get a 120V motor, WG1570, and replace the one on the T104. Then just use the terminals 1 & 2 to switch the power. The mechanism will then become a T103. Be sure a neutral and one of the motor wires is attached to terminal A (far left).
