Which wire color do i hook up to line 1 & line 2?

Question posted under 240volt R8806P101C timer.

240Volt line, both hot wires, line1 and line2, are identical so wire color doesn't matter and either wire can connect to either terminal.

R8806P101C terminal block has 4 screws. 1 2 3 4 from left to right.
240volt wire from circuit breaker connects to terminals 1 and 3
Wire going to 240Volt Load connects to terminals 2 and 4

I have the 59017 Mechanical. I set the pins and turned on in timer mode. It comes on at specified time, goes off after specified time, but then does not come on again the next night.

I don't have repair for defective timer:
If Load and Line wires are reversed, that could explain problem. Reverse timer red and timer black wires. Symptom of this problem: the clock dial stops rotating after tripper pin.

Troubleshoot run-through:
1) Use fingers and manually rotate timer dial several times and watch if Load turns ON-and-OFF
This will tell you if load is operational, and pins are set correctly.
2) Set slide switch to Timer.
3) Make sure timer is wired correctly. This timer needs neutral wire to operate clock motor. Open following link to see illustration and read about wiring. Line and load wires must be correct.
4) Check that wire nuts are attached very tight and there are no loose wires.

I have on and off switch for timer to red wires from pump two red also from timer two white a nd one black how do i enstall

Description of wiring is unclear
Timer is not identified.
Different timers install different ways.
Not all timers are made to control a pump.

Here's what I know:
1) You are replacing single-pole switch.
2) You want to control pump with timer.
3) You posted question under ST01C timer, but ST01C has 1 blue wire so you don't have ST01C timer.

Here's what I need to know to help you:
1) What HP shows on pump nameplate?
2) What color wires are coming from pump, and how did each wire connect to single-pole switch?
3) What buttons are on timer so I can identify timer.
4) What color wires are on timer.
5) What other wires are inside switch box other than wires going to pump.

I have a malibu ML 88T low voltage transformer. It was working fine and I saw the manual on/off and turned it, (i should have left it alone). The lights did not come on, so I turned the manual on/off...

You can do it yourself.
Anybody that knows 'hardwired' and observed timer is making humming sound can wire up a timer.
If M88T timer dial is not rotating, but power pack is making humming sound, then that says timer is receiving power but clock motor has gone bad.
There are no replacement clock motors for power packs.

To wire a new timer:
Click circuit breakers until the humming sound turns off.
Turn breaker back on to confirm that humming sound is associated with that breaker.
Buy a tester at local hardware and ask them how to use it.
Tester will give you assurance that power is off when connecting new timer.

Outdoors: put down dry boards to stand on, never stand on bare soil or wet/damp surface, don't touch anything metal and don't hold metal screwdriver in mouth while working on electric circuit. Wear gloves if you want. And don't sweat.
With 120volt circuit, as long as you are not grounded, which means that you are not touching soil, or anything that grounds back to soil, then you will not get electrocuted. You can get shocked only if power is still turned on at circuit breaker, and it will be surprising, but it won't kill you as long as you're not grounded. All electricity goes back into the earth to complete circuit.

Open the box where timer is hardwired.
Use tester on black wire. To confirm power is off.
Typical 120volt circuit: Black wire is Hot and carries voltage. White wire is neutral and completes the circuit back to ground. Bare copper wire is ground and serves as redundant safety.

Old 88T timer will be wired black-to-black, white-to-white, and green-to-bare copper.
Take photo of wiring to avoid confusion. Post photo on flickr and add a comment with link to photo for another pair of eyes on situation.
Cut off end of new timer wire, strip insulation with knife and attach wires same way previous timer was connected.

To install ordinary 120Volt outlet so timer can plug in: Buy outlet from hardware: Black hot wire connects to brass-colored screw, white neutral wire connects to silver-colored screw, bare ground wire connects to green-colored screw.

Dear Sirs, I try to change Intermatic E1343 solid state timer to normal 2 ways switch. I saw the cable in 3 colors : black, red and blue. do ou know the menaing of each cables? if you can email me...

I think you mean Ei343 instead of E1343.
I have manual for EJ341 and EJ343 that shows wiring for single-pole and 3-way.
I believe the EJ343 is wired same as Ei343 since Intermatic Load rating chart groups these timers together.

Load-rating chart:
Load chart implies this is 120Volt in-wall timer for inductive and tungsten loads up to 400Watts.

Now here's something to remember.
When any timer is wired for 3-way, the timer replaces one of the 3-way switches.
The other 3-way switch remains, but the other 3-way switch has to be rewired differently so that 3-way timer works correctly.
When removing timer from 3-way circuit, don't forget to re-wire the remaining 3-way switch so it works correctly.

To convert your timer to operate single-pole: Timer Black wire connects to Hot wire from circuit breaker. Timer Blue wire connects to wire going to Light. Red wire is capped off.

I have an old intermatic (1983) freeze guard that I am trying to wire into my pump timers. 4 wires are 2 for load and 2 for line in. 2 orange and 2 red. WHICH COLOR IS THE LOAD AND WHICH COLOR IS THE LINE...

There is not a set color code when it comes to that stuff. If the timer is still connected and there is power to it, turn the manual ON/OFF lever inside the timer to the OFF position. Using a volt meter set to at least 240 volts, test the wires. The set of wires that are still hot are the LINE wires.
If the timer has altready been removed, you'll have to _carefully_ separate all the wires so that they aren't touching anything and re-energize the circuit from the breaker. Then test the wires. The 2 wires that are hot after re-energizing the circuit will be the LINE wires.
