The wiring is incorrect. The wiring diagram for that timer is misleading. The 120 volt clock timer motor is connected internally to the "A" (neutral) terminal and the #3 terminal. The "A" (neutral) terminal is to the immediate left of the #1 terminal.
Here's how to do the wiring for your use, (assuming a 120 volt supply circuit and a 120 volt light circuit):
Connect the incoming power (line) black wire to terminal # 3. Connect the incoming (neutral) white wire to terminal "A".
Connect the outgoing (load) black wire to terminal # 4.
Connect the outgoing (neutral) white wire to terminal "A".

    thekids2980: Measure the voltage between terminal #3 and terminal A. You should have 120 volts. If you have 120 volts then the timer motor is bad. If you don't have 120 volts, then check the circuit breaker in the main panel. That circuit may also be on a GFCI. Look for a GFCI receptacle that may have tripped.

    ecj2: One wire from the timer (clock) motor (pick one) goes to terminal A. The other wire goes to terminal #3.

    Also, for anyone else who may be reading this thread, the instructions are for the T103 ONLY. If you have a different model, please post that model #, as different models have different wiring.

    thekids2980: Are you using a T103? The wiring diagram for the T103 shows the clock motor connected to terminal #3 and terminal A:

    Just so there is no confusion for others who may read this thread, a T101 clock motor connects to terminal #1 and terminal A.

RT3 series has T104 240 volt timer -or- T103 120 volt timer, -plus- low voltage transformer for pool light.
The circuit breaker can be used for transformer, or another outlet or nearby light etc, or it can be used for a T103 120 volt timer.
To trace the wire back to breaker box.... open you main panel and start turning off breakers one at a time and label the panel.
See if you have single breaker or double breaker supplying power to pool equipment.

My Intermatic T103 Indoor 120-Volt 40-amp timer emits a constant peeping sound


Intermatic T103 is mechanical timer with moving gears.
Timer makes audible sound when tripper clicks on-off, but it should not make constant noise unless gears are causing noise.
Turn off power and spray WD-40 on gears and see if problem continues.
WD-40 vapor is extremely flammable hydrocarbon when sprayed, and should not be sprayed on live electric circuits.
If problem continues, turn off power, pull mechanism out and spray WD-40 on plastic gears of clock motor.
Open following links for illustrations of clock motor and removing mechanism.

We install the timer and it does not work automatically. We can switch it on only manually


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.

A FRIEND OF MINE HAS A T103 TIMER FOR HIS OUTDOOR SIGN. I RECENTLY INSTALED A NEW CLOCK MECHANISM, HOWEVER IT WILL NOT KEEP CORRECT TIME TO TURN THE SIGN ON OR OFF AT THE PRESET TIMES. IS THERE A WAY TO...


1) There is no speed adjustment on timer clock motors.
They are manufactured for 60 Hz, which is the controlling factor for motor speed.
60 is the number of cycles per second that AC electricity oscillates, caused by a turbine spinning inside magnetic field at power plant. This speed is very constant, and so clock motors keep correct time for years or decades.

2) A loose wire or loose circuit breaker could cause motor to lose power at times.
Clock would appear to run slow.
Check terminals. Make sure no insulation is sitting under the screw-down plate on timer terminals.
Tighten wires very tight against copper wire.
Move Hot wire to another circuit breaker and see if problem persists.
Tighten screw on neutral wire on neutral busbar inside breaker box.

3) Problem could also be bad clock motor for some reason.
For $16 replace T100 series 125Volt clock motor
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

4) Trippers contact a lever, make sure lever has bit of grease so trippers are not hanging on the lever. Off tripper moves lever one direction, ON tripper moves lever other direction.
Double check operation of lever by moving override back and forth.
Override should snap crisp and clean, and not be extraordinarily hard to move.

I have an Intermatic T103 DPST timer installed now (120v). The clock mechanism has failed. I bought Tork 1103 guts to replace it. The wiring is a bit different. Can u map for me which wires go to which...


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

I have a T103 that replaced a old Tork timer. my problem is i have 3 wires black,red white where do they go?


T103 has 120volt clock motor.
If your circuit is 240volt, then change T103 for T104.
Electricians test before hooking up wires.
Use ordinary tester.
Separate wires and turn on power.
Test each wire to bare ground wire.
Tester will light up on hot wire.
In absence of bare ground, test each wire against other wires or against grounded surface to isolate the hot wire.
Hot wire connects to terminal 1 on T103 timer.
Now test hot wire to other wires (exclude bare ground)
Tester lights up on Neutral wire.
Neutral wire connects to terminal A.
The last wire must go to Load, so connect this wire to terminal 2.
Bare ground wire connects to green ground screw.
Turn on power, click manual override to check if load turns on and off.
Lift and rotate yellow dial until current time lines up with silver pointer.
Put trippers on outer edge of dial at on-off times.
Off tripper are brass colored.
Each tripper is marked.
Minimum 1 hour on-off period.

I having troble with my t103 timer to turn the lights on manualy i try to set the timer but for some reason doesn't work what can i do ???


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.
Grainger sells 125V clock motor:
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

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.

Set the clock for current time, but lights come on 3 hours before the on tripper.

Add a comment if you have different brand.
Current time lines up with silver pointer.
Sounds like silver pointer is not at 6:00 position
geno_3245_70.jpg

Review timer operation:
T-103 timer dial rotates around until tripper contacts mechanical lever:
On tripper pushes lever one direction until it clicks, OFF tripper pushes lever other direction.
Each time lever clicks into position, manual-override lever also moves back and forth.
Manual override is connected to same lever that trippers push.

Troubleshoot:
Watch if timer functions as described above.
Click manual override and check that lights turn on-off correctly.
Add a comment if timer is doing something other than described.

T103 clock not working


Please read all of this post. You may burn up the 120 volt T103 timer motor is you are not careful.

The statement: "I have 120v board with 120 constant and 240 timed" is not very clear to me as to what you mean.

In US residential wiring, the white wire is not always the "neutral;" The white wire is sometimes used for 240 volt circuits.

We cannot tell you how to wire your timer unless we know _exactly_ what you have.

If your incoming supply cable (from the breaker box) has 3 wires (black, white, and bare), there are two scenarios:

1...If the voltage from black (hot) to white (ALSO hot in this case) is 240 volts, and you have only 3 wires (black, white, and bare), then the T103 is the _wrong_ timer if you are trying to control a 240 volt load. You should use a T104 timer.

The T104 uses a 240 volt timer motor and the T103 uses a 120 volt timer motor.

2...If the voltage between black and white is 120 volts, then you will only be able to control 120 volt loads; then the incoming black supply wire is connected to terminal 3 and the white (neutral) wire is connected to the "A" terminal. The bare equipment grounding wire is then connected to the "GR" terminal.

To show the difference, if you are trying to control a 240 volt load, to use a T103 and wire it _correctly_, you would need to have a incoming supply cable with a total of 4 wires (black, red, white (neutral), and bare) Black to red would be 240 volts. Black to white would be 120 volts. Red to white would be 120 volts.
The connections would be as follows:
White (neutral in this case) to the "A" terminal
Black to terminal 1
Red to terminal 3
The 240 volt load would then connect to terminals 2 and 4
Both the bare equipment grounding wires are connected to the "GR" terminal.

Since you did not mention a red wire, I can only ASSUME that this is not the case.

Sorry, we can't tell you how to wire this timer based upon assumptions.

So, what do you have?
