Timer is wired incorrectly.Single pole wiring does not use the red wire. Red wire is capped off.Copy following link to see specific wiring illustrations for ST01C timer:http://waterheatertimer.org/ST01C-program.html#wireRelated but not same problem:In some 3-way wiring installations, if the power goes out, or if the bulb burns out, the timer can click. The lights do not blink because power is out or bulb is bad. Simply flip the 3-way switch to stop clicking sound. Then change light bulb, or wait for power to resume.

Old timer: Intermatic EJ500 & ST01C timers have a battery. Battery operates the clock motor. Red wire is for 3-way circuit [a hallway with 2 switches is a 3-way circuit].

Utilitec timer, clock runs on 120Volt circuit instead of battery. So clock has to have power.

How to connect wires:
Black timer wire connects to hot wire from breaker box.
Red (or blue) timer wire goes to landscape lights.
White timer wire connects to white neutral wire [or if no neutral is available, connect to bare ground wire].
Green timer wire goes to bare ground wire.

How to find black hot wire and white neutral wire inside box: Disconnect and separate wires so you can test. Use ordinary tester. Power is on. There is only 1 black hot wire inside each electrical box. Test each black wire to bare ground until tester light comes on > that identifies the black hot wire. Next, test black hot wire to white wires until tester light comes on > that is the neutral wire. Exception: This test does not necessarily work with 3-way switches since they reverse each time switch is thrown.

You posted under the ST01C timer.
ST01C has black, red and blue wires, and has a battery to run the clock.

You have black, white, red and green.
So your timer has an electronic clock and no battery.

Let's go through the wires one at a time.
You can add a comment and I will help further if needed.

Old switch has 2 black wires.
One of these wire is black-Hot
The other wire is black-to-Load (load is your light, fan, motor)

Black-Hot connects to timer-black wire
Black-to-Load connects to timer-red wire
NOW ... if these wires are reversed, the timer will not operate, so simply reverse the wires.

There are two wires to go:
Timer-green wire goes to bare copper wire.
Timer-white wire is the wire that runs the clock inside the timer. This is just like plugging in your alarm clock so the clock runs.

The timer-white wire connects to the other white wires located inside the box.
These white wires are usually twisted together and covered with a wire nut.
So untwist the wire nut and add the timer-white wire to these wires.
What if your box does not have these other white wires?
Then in that case, connect the timer-white wire to the bare copper and the clock will run.

Hello, I bought an in door smart digital timer (G.E.) or Jasco product for my front porch light. I hooked all the wires as instructed and programmed according to instructions. I have a two wire system, so i left the green wire unattached. The light comes on but flashes very fast. What's up with that? This is the second one i've replaced, the first one did the same thing!. Whats wrong?
Thanks,...
