SOURCE: Lights dont stay on

I must assume that when the light goes out (quickly after it goes on) that you can turn it on again very soon and the same thing will occur. This cold be an overload; that is, the timer is designed for handling 300 watts (as an example) and you have 400 or more watts of lighting, therefore the timer is saying this is too much and cutting off. Or there can be a bad light that is drawing too much electric such as a fluorecent light with a bad ballast. Or, if this outlet where the switch was, has only 2 wires that went to the old switch (and no other wires) then you may be feeding current into the new timer switch and shorting it out. The essential point is: is this switch outlet box with only 2 wires where the black and white both went to the switch, or are there more wires where 2 blacks (or a black & red) went to the old switch and the white wires are nutted together and not attached to the old switch.
You need to determine the wiring system within the box before you can determine how to apply them to this timer unit. Remember, the timer needs a nuetral and ahot just to operate, then it needs to feed this operated conrolled electric to the light via the red output wire. Regular switches do not work in this manner.

SOURCE: installing a GE digital wall

Review:
Black goes to Hot wire from breaker box
Red wire goes to Load (light, fan, motor)
White wire goes to Neutral
Green to bare copper ground wire

Orientation:
Your original switch had 2 wires plus bare ground.
One of these wires is Hot, the other goes to Load.
You said original wires are Red and Black

How do you find Hot wire?
-Your original switch had 2 wires.
-Remove timer from box.
-Pull original 2 wires out where you can test them
-Turn on power
-Use regular tester
-Tape tester leads to wood sticks so your hands stay away from voltage
-Power is on
-Test each original wire to bare ground wire
-When tester lights up, that is Hot wire ... this wire connects to Black wire on timer
- The other wire goes to Load so it connects to Red wire on timer

How to test for Neutral wire
Test Hot wire to your white wires - No need to untwist them.
When tester lights up, that is Neutral
White wire from timer connects to Neutral.
Green goes to ground wire.

How to reset timer
I'm not sure which timer you have. Probably GE 15086. Reset is small round button below HOUR button. Use paper clip and push-in reset until timer flashes 12 o'clock.

SOURCE: I the manual wiring doesn't match what I have in

I test these timers.
GE 15071 timer has internal clock that runs on electricity. That's why timer has extra wire.
Intermatic, GE, Tork, Leviton, Sylvania, Woods, Utilitec etc in-wall timers each wire the same way.
The only tiny difference is GE doesn't have green ground wire.
http://waterheatertimer.org/Program-wire-Utilitec-0192773.html

Here's what to do:
1) Old switch has two screws (excluding green ground screw)
One screw on old switch has 2 black wires >> these are hot wires > timer black wire connects to these hot wires. This will power the timer.
2) The other switch wire connects to timer red wire. This will send timer signal to lights.

3) Timer white wire is for the timer clock.
Timer white wire connects to other white wires that are twisted together and covered with wire nut >>> these are neutral wires, and now timer clock will operate
4) For EZ connection to other white wires, strip back another inch on timer white wire so stranded wire can wrap like a candy cane around solid copper wires. Then twist wire nut on very tight.

5) When wiring is complete, push door on timer for manual override. Lights should turn ON-OFF. If lights do not turn on, reverse timer red and timer black wires. Make sure outdoor bulbs are working.

SOURCE: I am replacing an old SS5 timer with this new one

Open following link to see clear drawing and instructions for wiring ST01C timer.
Page also has EZ programming steps:
http://waterheatertimer.org/ST01C-program.html#ST01C

Red wire is capped.
Blue wire goes to Load (wire to sconces)
Black wire connects to Line wire (wire from breaker)
Green wire goes to ground.
If you are uncertain about Load and Line wires, just connect them either way, turn power ON, push on-off button, it lights don't come on, then reverse wires.
I have tested this timer, and information here is correct.
Don't forget to install CR2 battery, otherwise display will not show.

SOURCE: I bought a Utilitech Self

The reason there is 2 black in the wall is because a standard line breaking switch was used. Meaning the hot side of the light was the black wire once broken light goes off. You would hook the black from switch to black in wall and white from switch to other black in wall green is ground and red put wire nut on. Red is for a 2 switch system. Where one of two switches in same room controls same light. Its not needed. Take caution when doing this trun light on goto breaker box and flip breakers till you find the right one that powers that light. once lights off then do your thing replacing.

I am replacing a intermatic t101r with a tightwatt timer. the t101r has 5 terminals wired, the tightwatt only has 4


Hello Barbara.
You dont have T101R timer. Because T101 has 3 terminals.
Remember any Intermatic timer can be replaced into the T101 enclosure.
First step, Identify your voltage.
Second step, identify if you are controlling a 2-speed pump.
Third step, identify the Intermatic timer by looking at clock motor and wiring.

T101R timer has 3 terminals, and has WG1570 120Volt clock motor.
T103R timer has 5 terminals and WH1570 120Volt clock motor
T104 timer and T106R timer have 5 terminals and WG1573 240Volt clock motor
Copy following link to help identify your specific wiring.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

Terminal A on Intermatic could be Neutral or Hot depending on what has been done to alter the timer.
Generally the tightwatt timer wires very similar to P1353 timer.

Yes.
Timers usually don't last more than a few years, unless you buy the heavier duty box timers that last decades.

I've installed a 60-minute Woods timer 12842 (digital) in my garage but it switches itself off prematurely over and over. I notice when it is on the little green 10min timer light clicks & dims ever so...


Open following link to identify timer for sure, download on-line manual, and read wiring instructions.
ttp://waterheatertimer.org/Woods-timers-and-manuals.html#59000

1) Manual says 1000Watt Tungsten (incandescent) and 1000Watt Ballast (fluorescent)
2) Timer is powered by electric circuit and not internal battery, so cold garage temps will not affect operation
3) Check wiring against instructions shown on link above, except your other timers work fine, which indicates correct wiring.
4) Buy cheap circuit analyzer at home center, and test receptacle on same garage circuit
5) Try moving known-good timer to same location and see if problem persists.
6) I test timers, and some in-wall and plug-in timers arrive defective, and some go bad quickly, most have 1 year limited warranty, some last 5-7 years.

When I press the timer to go on my three outdoor lights go on and off, timer clicks that way too


Timer is wired incorrectly.

1) If you have battery-operated Intermatic EJ500 or ST01C, with red, blue, black and green wires:
Then red wire is where blue wire should go. Swap blue and red wire.

2) If you have Aube battery-operated timer, add a comment and say if you are replacing single-pole or 3-way switch. And say where each wire is so far.

3) If you have GE Tork Intermatic UPM Woods Brinks Hagar Pass-n-Seymour Stanley Westek in-wall timer, with red, black, white and green wires, then you probably put red and white wires together.

Heres how to wire timer

1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires. Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.

The on/off lever on my t103r has worn down , and the timer dial posts no longer switch it on and off . can i replace that part . thank you , Don Henrichsen / Sherman Oaks , California


I think trippers have worn down.
Tripper are made of softer metal than on-off lever.
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

That being said, if you have gone through several trippers and timer is old, then on-off lever can wear out.
Except for 125V clock motor and on-off trippers, there are no repair parts for T-103.
Buy new T103 and swap mechanisms without changing box.
That way you don't have to buy more expensive T-103R outdoor timer.
Mechanism snaps out with metal spring located at top inside box.

I purchased T-103 last week from Lowes.
Surprised that Lowes carried all 3 T-100 series timers:
T-101 125V with terminals A 1 2
T-103 125V with capability of controlling 120-or-240V circuits with terminals A 1 2 3 4
T-104 240V with terminals A 1 2 3 4
