Wow, you bought one hell of a thermostat to run just a Your going to place on wire on R and 1 wire on W/AUX. R is your common power in and W/AUX is for a single stage cooling unit.

I have had a T103 running my pool pump for the last several years. All of a sudden the timer would switch on but not off. It was like the dial did not have enough torque to force it to switch and would...

1) T103 is 120Volt timer that can control multiple loads and different voltages..
If new timer dial stops turning after the tripper passes, then wiring from circuit breaker is probably reversed with wiring going to pump.
Open following link to identify correct wiring:

2) Add a comment for specific help with wiring, and I will respond.
Give details of pump voltage, and description of each wire.

3) To fix old timer, Replace 3-watt, 120Volt WG1570 clock motor.

I just purchased Malibu ML 600 TW transformer, and ran wire and attached lights, but I can't get any of them to work. Perhaps I'm wiring it incorrectly? How do I test the transformer to see if it is...

Malibu website
Malibu manuals

The power pack has a humming sound >> put your ear close
Plug in a hair dryer on same plug to see if you have power
Check the GFI tripper in bathroom and kitchen
Plug power pack directly into receptacle (no extension cord)
It is hard to believe you got every light wrong >> the light connections are pretty fail-proof today

1) You can test the transformer by rotating manual override counterclockwise >> that's the on-off switch
2) You can test transformer by seeing if clock dial rotates with passing time > the clock must rotate
3) You can check if wires have power > disconnect wires > use another wire to scratch across both terminals to see if there is a spark

4) Did you put the red-and-black tripper pins on the dial? Red = ON Black = OFF

5) I think you forgot to set the time of day correctly
- put in tripper pins.
- rotate center dial clockwise to present time
- now, rotate dial two more full rotations and come back to present time

If the dial will not rotate or transformer does not have power, then the transformer is defective.

I am unable to get a dial tone on the main set or the two handsets. I have punched the Line 1 and Line 1 buttons; I have punched all the buttons...but there's no dial tone and friends have called in and...

My telephone troubleshooting starts with an old corded phone as a test device. First, unplug the base unit and plug in the old phone. Do you get a dial tone? Try a new phone cord and check for a dial tone. If the new cord gives a dial tone, check if the cordless base unit gets a dial tone with that cable. If the cordless phone does not work and the older phone does, then the phone needs service. Do make sure the cordless phone base has power and that the handsets have good batteries (NiMH AAA) that are properly positioned. + up on the right hand side of the handset battery compartment and - up on the left. Do not touch the contacts on the handset or the ends of the batteries.

If you do not have a dial tone with the test phone, find where the phone service comes in. Open the service box and check how it connects. Newer service boxes use RJ-11 jacks (same as inside jacks) so plug your test phone in at that point. If it doesn't have this jack, there is a special connector that your phone company techs will have. Call and ask them to check the line. Do you have a dial tone? If no, call your phone company for service. If yes, then you have an interior wiring problem. Look at any exposed wiring for damage. Check if other phone jacks work. If only the one jack is not working, open up the outlet and look for a wire that has come loose or broken. Depending on the type of outlet, either strip some more of the insulation from the wire (if needed) and resecure it under the screw. For the other type of jack, you use a tool to press the wire into the jack (no need to strip the insulation). If the cover lifts off you can replace a loose wire. If the cover doesn't come off, then you would need to cut off the keystone and replace the entire keystone. (A plastic version of this tool will come with a keystone jack and better versions also sold separately at many hardware stores near where they sell other home wiring accessories.) Then replace the cover for the keystone. In either case, then retry with the test phone.

2 wire RJ-11 are pin 1 to position 3 and pin 2 to position 4. 4 wire adds pin 3 to position 2 and pin 4 to position 5. has a picture with the current standard wire colors for the connections.

Any other problems that occur on both phones indicate a break in the wires in the wall.

Your phone company will service the problem for a fee.

I found the manual as a PDF: .

I hope this helps.

the only thought that comes to mind is to re-check your spark plug gap, the reason is that if the gap is slightly larger, plug efficiency will drop, thus fuel economy and power, please confirm that some platinum plugs the gap is not adjustable, (.044 thousands) good luck!

Attic fan motor replacement

It sounds like you are replacing a two speed motor with a single speed. Check the side of the old motor and see if it has high and low speed wiring schematics. If so you need to replace with same model number. Good luck!
