I installed a manual timer switch (Intermatic, model no. T103, Double Pole Single Throw Clock Motor: 120V 60HZ ) at 11:00am today and my dials was set to come on at 7:00pm at night and cut off at 7:00 am. When I left the lights was on will the timer start working 7:00am the next day automatically adjust itself to shut-off the next day at 7:00am. I fell like I left something out? Thank you, Dino M. Pernell Sr.

T104 timer is 240Volts.
Not 120Volt
You can convert timer into 120V by changing clock motor from WG1573 to WG1570. This action will convert the T104 into T103.

The T104 timer can be wired many different ways:

Add a comment with specifically what you are connecting to timer, and I will comment back with more detail as needed.

Check that the dial is keeping correct time, you might need new WG1570 clock motor.

You posted under T103 Intermatic 120V timer.

Sounds like you wired the timer wrong:
Timer has 120V clock motor and requires Hot from breaker on terminal 1, and Neutral from breaker on terminal A. This will power clock motor.
If you have any of the wires reversed, timer will do what you describe.

T103M is 120Volt timer that can handle all the Christmas lights.
Minimum on-off time 1 hour.
Rotate dial until current time lines up with silver pointer.
Set on-off trippers on dial.
Let's go step by step.

1) T103 has terminals A 1 2 3 4 >> terminals are also called poles
DPST (double pole single throw) and SPST (single pole single throw) are two different ways to wire this particular timer.
T103 timer can be wired numerous ways... but your project is not complicated.
DPST means timer turns off two terminals/poles (double pole) with each click/throw of timer switch (single throw)
SPST means timer turns off one terminal/pole (single pole) with each click/throw of timer switch (single throw)

2) T103 timer is ST single throw, all the lights come on at same time. So this timer is 1 channel.
1 channel timers are either ON or OFF and everything turns on-off at same time.
You cannot stagger on-off times with 1 channel timer.
If you want upstairs and downstairs lights to come ON at different times, you need two timers .. or a 2-channel timer (which is different ballgame).

3) T103 timer has 120Volt clock motor that is connected to terminals A and 1.
Look at timer and you can see small white wires connected to A and 1 terminals that power 125V clock motor.
When wiring this timer, your wires from 20 amp breaker box connect to terminals A and 1.
Black hot wire from breaker must connect to terminal 1
White neutral wire from neutral busbar must connect to terminal A

http://waterheatertimer.org/B220C.html

4) Terminal 1 must be hot so when timer switch clicks ON, it sends power to terminal 2.
Your load wires connect to terminals A and 2
I made simple drawing of SPST option showing how to wire T103 to 3 receptacles.
Fixya downgrades image so it's hard to see.
Hot wire to terminal 1
Load wire to terminal 2
Neutrals on terminal A

If you want to wire timer for DPST, which is necessary for loads exceeding 2 horsepower (1500 Watts) on each terminal
Notice black jumper wire from terminal 1 to terminal 3
Notice all white neutral wires to terminal A

I made third image for guy who was wiring high amperage blowers, that show wiring for two T103 timers. Having two timers would let upstairs and downstairs lights come on at different times.

T-103 has 120V clock motor with 5 terminals A 1 2 3 4
Tork 1101 has 120V clock motor with 4 terminals L 1 X 2

T103 is DPST and can control one-or-two 120Volt loads, or one-or-two 240Volt loads.
Tork 1101 is SPST can control one 120Volt load

Common ground between these timers one 120 Volt load
Changeover for one 120 Volt load:
White wires T103 terminal A go to Tork terminal X
Black wire T103 terminal 1 goes Tork terminals L and 1 (there is brass connector plate that connects L and 1 - if connector is missing, jumper between L and 1)
Black wire on T103 terminal 2 goes Tork terminal 2

If Load requirement is greater than T1101, Grainger sells T103 clock motor for $16

T1101 wiring manual

T103 Intermatic timer has 120Volt clock motor and can control 120V or 240V Loads.
Wiring for timer is shown on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

Troubleshoot T103:
1) Manual override is working correctly, and it snaps crisp and clean, and Load turns on-and-off.
That means timer is basically good.

2) Next look to see if yellow dial is rotating.
If dial is not rotating, then 120Volt clock motor needs to be replaced.
Take photo of wiring and mark wires before starting.
Remove two white wires connected to screw terminals 1 and A.
Snap timer mechanism out of box, clock motor is on back of timer.
Use small star screwdriver to remove old clock motor.
Reattach white wires on terminals 1 and A, tighten screws very tight.
Reset current time: lift and rotate dial until current time lines up with silver pointer.

3) If dial is rotating, but gets stuck at certain times, or runs slow, then replace clock motor.

4) If dial is rotating, and trippers are attached to dial, but timer does not turn ON, then trippers are worn down and need to be replaced.
Grainger sells the T103 trippers
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

5) How Intermatic mechanical timers work:
Dial with ON-OFF trippers is rotated by clock motor.
Trippers on dial contact ON-OFF lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Lever moves electrical contacts on back of timer that turn Load ON-OFF.
Manual override lever clicks back and forth with each ON-OFF action.

Maybe-bad news.
The link below shows wiring for the T-104, T-103 and T-101
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

For a 240V installation, the correct timer is the T-104, not the T-103
This is because the T-103 clock motor is 120V, and requires additional neutral wire on terminal A
The T-104 clock motor is 240V, and requires only the two hot wires and does not require a neutral.

I suggest you exchange timers and get the T-104
Or run another wire to nearby 120V receptacle and connect Terminal A to the white wires in nearby receptacles. This will give you the neutral that is needed for the clock.
In the absence of a Neutral wire, you can work-around by connecting ground wire to Terminal A >>> but this is NOT Code. You might use the ground wire as a temporary work-around until running additional neutral wire.

The motor for the timer is shot you will have to replace the unit .Sorry

yes u will, but u will have to make sure one of the motor wires are hooked up that way also, in case it has been moved, here is a link with the diagram u need
