I have installed the Utilitech timer switch # 0141224 with all of the wires connected as they are explained in the installation packet. The timer works and turns on the lights, however it only turns on 4 of the 6 lights it is powering? The timer is installed on 1 light switch that powers 6 landscape lights outside. This 1 light switch is part of a 2-gang unit and the wires are set-up as follows: Black Timer to Black Hot wire loop from other light switch in gang unit, Red Timer to black external lights (the one's I'm powering), White Timer to white bundle in back of box, Green Timer to bare copper in back of box. Any ideas what I am missing or if I wired it incorrectly? Is the white bundle in the back of the box (about 6 wires) the wires that go to the outside lights? If so, could it be that the white timer wire is only touching 4 of them and that be the problem?

Thank you for your feedback! I was hoping that was the problem but unfortunately I'm still having trouble, I verifed all of the wires are touching in the white bundle (and I was incorrect, it's only 3 wires plus the timer white for a total of 4, not 6). After verifying all are touching and connected securely I tried it again and no luck.

Do you think it's possible that the timer does not have enough voltage/power to control 6 outside landscape floodlights? Could that be the problem?

All connections look good and all are connected accurately per the instructions and your guidance. I tried the reset button on the timer and I tried resetting the GFCI outlet but nothing seems to work?

When I turn the timer on 4 lights come on but 2 do not. Bulbs are good, connections are good, and wires are good. What am I missing? Thank you for your feedback!

(1) I tested Utilitec timers, and some arrive defective:http://waterheatertimer.org/Program-wire... (2) Utilitec load rating is 1875 watts incandescent, same as ordinary 15 amp on-off switch (3) Six 150Watt floodlights is 900 watts, so load rating SHOULD be okay. Substitute 60 watt light bulbs and see what happens. (3) I don't know what troubleshooting has been done, and don't know if all the lights are on one cable. If there are two cables, I would determine which white neutral wire(s) is connected to outdoor lights, and examine each circuit separately. (4) Turn on timer and remove light bulb and test output at bulb socket with multimeter. Tape multimeter leads to woods sticks for safety. (5) Try installing ordinary on-off switch and see if same problem exists. (6) Buy 15071 or 15086 7-day timer at Home Depot, or for astronomic function, GE15312, and see if same problem happens with different brand timer.
