You should be able to wire the blacks on the two terminals on the left side and then the other two wires on the right side terminals...

The blacks are hot in one out..and the whites or reds should be the one in one out...

grounds should be green or bare,,, hook them to the case or ground screws...

make sure oyu have 240 volts to this timer... the motor is 240volt...

here is the timer schematic

How to change clock on intermatic t101p

Step 1:

Turn power off to time clock

Step 2:

Remove the wires, but mark them/label them from where they came from! Should be 4 of them. 2 on the posts marked Line and 2 on the posts marked Load.
Line wires are coming from your power source and will usually have the small white wires with them to provide power to its internal clock motor.
Load wires will go to the motor.

Step 3:

Near the top on the left side you will see a clip style holder. That holds/locks the clock into place. Push up on that clip and with a free hand grab the clock mechanism and pull. The clock should come down and out as you pull.
Take new mechanism and find its resting hook at bottom and just reverse the step above. It should slide into place & lock under that clip. You will hear a click/snap.

Step 4:

Replace the wires that you marked: the 2 Line wires and the 2 Load wires. Check the schematic and ensure that the positions are the same as old or not.
Some older clocks had this schematic: Line - Load, Line - LoadSome newer clocks had it this way: Line - Line, Load - Load

Step 5:

Tighten the screw nice & tight and ensure that you have line wires on the line post and the Load wires on the Load post.
You should be golden.

What configuration do the output power wires look like. Do I connect to 3 and 4 , slots etc. What is meant by "load" in the instructions?

1) You posted under ET104C DPST (double pole single throw) 24-hour 4-ON and 4-OFF per-day selectable-voltage timer
DPST means that timer will turn off two wires going to 240Volt Load or two separate 120V Loads

Open following link for example Intermatic ET series wiring diagrams and manual:

2) Load means whatever electrical device is controlled by timer. ie fan, light, motor, pump, alarm-bell, water-heater, bowling-ball-machine etc.
Line means cable coming from breaker box.

3) If you have a different timer, then add a comment with photo of inside of timer door for possible identification and complete answer.

4) Selectable voltage means you have to choose voltage.
Timer come preset for 240Volts.
If you have 120V 208V or 277V, then follow the vague instructions shown on page 2 #2 of manual.

5) Do not apply voltage to this timer before matching selectable voltage setting with circuit breaker voltage.

6) ET104C has 6 terminals and can be wired many different ways depending on Load voltage, etc.
This timer can do a lot of different things.
If you have ET102C with 4 terminals, then add a comment and clearly explain voltage, color of wires, and what breaker you have and what Load you are controlling for best answer.

7) ASSume you have 240Volt cable coming from breaker box, and that you are controlling a single 240Volt Load like a water heater or pool pump.

240Volt cable from breaker will have 2 hot wires called Line 1 and Line 2
Line 1 black wire will attach to both terminal 1 and terminal 3 (use a jumper wire between terminal 1 and 3)
Line 2 red or white wire will attach to both terminal 2 and terminal 5 (use a jumper wire between terminal 2 and 5)
Your 240Volt Load will also have 2 wires.
Load 1 black wire will attach to terminal 4
Load 2 red or white wire will attach to terminal 6

Hi! Please help me. I am having trouble connecting the wires from my dead 220v T104 pool pump timer to a new 220v T104 timer. The old timer had posts marked G 1 2 3 4. The new one has posts marked L 1 X...

Open following link for T104 wiring diagram:

Your new timer is L 1 X 2, so that is not Intermatic T104.
You might have GE/Tork 15061 that fits into Intermatic box.
First thing to check is if new timer is 240Volts to match old T104.

If new timer is 240V, then here is crossover:
"Old 1" goes to new L >> and notice that L and 1 are connected by brass bridge. If bridge is missing, add a jumper wire between L and 1 on new timer

"Old 2" goes to new 2

"Old 3" goes to new X
"Old 4" goes to new X

T104 Intermatic timer is SPDT single pull double throw, so it turns off both wires going to Load.
New L1X2 timer is SPST single pull single throw, so it turns off one wire going to Load, and that's why old 3 and old 4 both connect to terminal X.

If this is too complex, then add a comment or buy new trippers and a new WG1573 clock motor and repair T104 for $20.

I have a wh21 Intermatic water heater timer. I installed the shut off and on switches. They are not working. I opened a manual and it stated to make sure the dial is pushed all the way in. I spun the dial...

You might have your Line and Load wires reversed.
Line wires come from circuit breaker.
Load wires go to water heater.

WH21 wiring: There are 2 Hot Line wires coming from breaker box that connect to terminals 1 and 2.
WH21 is SPST and turns off one Hot wire going to Load. So Load wires connect to terminals 2 and 3. Terminal 2 has 2 wires: 1 Line wire and 1 Load wire.

Keep in mind that WH21 is 25 amp, 2Hp 240Volt timer that will work on water heaters up to 4500 watts. Look at label on side of tank to see wattage. All appliances and motors have labels.

Larger wattage water heaters require 30 amp water heater timers as shown following page:

How do you wire a intermatic t103

I'm looking at the T-103 sitting here in my office.
Terminals are labeled: A 1 2 3 4
I have about 10 different Intermatic timers on the shelves & each is a bit different

The T103 has a 120Volt (or 110V) clock motor
You need a white Neutral wire to operate the T103 clock

120V: Let's say your Load (light, fan, pump) is 120V
The white Neutral from breaker box connects to Terminal A
The 120V black Hot wire from breaker box connects to Terminal 1
The black wire going to Load (fan, light, motor) connects to terminal 2
The white wire going to Load connects to terminal A along with the Neutral
Ground wires connects to green ground screw
If your wires from breaker and wires to load are wired in reverse, the timer will turn ON the Load but the timer will not shut the circuit OFF.
To test which wire is Hot and Neutral, look at explanation at bottom of page.

240V: Let's say your Load is 240 Volts (or 220 Volts)
The clock motor is still 120V so you still need a white Neutral wire connected on Terminal A
Now you have 2 Hot wires coming from breaker box
Hot wire 1 from breaker box connects to Terminal 1
Hot wire 2 from breaker box connects to Terminal 3
Wire 1 going to Load connects to Terminal 2
Wire 2 going to Load connects to Terminal 4
Ground wires connects to green ground screw

What if you don't have a Neutral wire and you are wiring a 240V circuit?
240V circuits normally have 2 hots and a ground, but no neutral
Buy the T-104 timer
The T-104 has a 240V clock motor
Wiring for the T-104 is exactly the same as 240V wiring shown above for T103 EXCEPT there is no Neutral on Terminal A, and Terminal A is bare

How to test which wire is Hot
Test requires wires with live electricity >>> this is not advisable without precaution
Stand on dry boards, do not touch anything metal, wear dry clothes, do not hold screwdriver in mouth, wear gloves, tape tester leads to wood sticks so hands are away from power
Remove wires from terminals
Separate wires so they can be tested
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire(s)
If circuit is 120V, then there is only one Hot wire
If circuit is 240V, then 2 wires will test hot to ground >> these wires will be Hots 1 & 2
Test assumes circuit breaker is functioning normally.

How do you test for neutral?
If you have 120V line with only 1 hot wire, then one of the white wires will be Neutral?
Test Hot wire to each white wire
Tester lights up on neutral

Intermatic timer 2-wires in & 2-out. I have "A" neutral, line 1 and load #2. 2-wires in go into load and line. Out do I go neutral and line 1?

You did not give the exact timer type, but most Intermatic mechanical types have more or less the same terminals:

A - Neutral input and load - together
1- Input - Hot Wire
2- Output - time dependent Hot Wire - to load
GRD - Ground can or can not be connected.

I hope it will be useful for you.

I have an mid 90's Apollo Spa with a mechanical timer for the heater and pump. It has little tabs for each half hour of the day. My problem is that it has started to run slow. Over the course of a day...

The motor that drives the clock has a cog that drives the mech. This has probally worn and you will need a new gut for your clock. If this is a yellow dial it is probally a Intermatic timer.If you get the model number off the clock Home Depo can probally fix you up. The wires may not go to the same place's so be sure to wire to new specs. Two wires in are from the breaker and will be the line wires and the two that go to the motor are the load wires. Good luck.

How to wire an intermatic eh40 water heater timer

Note that the "IMPORTANT!" paper insert that came with my EH40 shows one small jumper between 1 & 5 and the second small jumper between 2 & 3 (and, of course, the jumpers aren't really long enough to reach from 1 to 5!). Jumping 1&3, 2&5 makes more sense and matches the labeling on the plastic insulator piece...
