ET103C is discontinued digital electronic timer.
Copy following link to idcentify timer:
Always check battery first... located under the buttons and above the wiring pull-out tray. Use reset button to reset after battery change.
Test for 120Volt across terminals 1 and 2 should show at least 80% rated voltage,
Add comment and say if this is freshly installed timer, of if timer worked before.
Also add if circuit is 240Volt, and what size breaker, wire and HP motor

Horn doesn't; work fuse is good. Mitsubishi montero sport 2000

Did you check the fuse circuit for voltage? Use a test lite or something. The fuse circuit goes hot with key on. Even if the fuse is good, if no voltage on the fuse circuit, the circuit is still dead.
The wiring circuit in the steering column and horn switch are the ground circuit for the horn relay.

I have a kenmore 790.9021 electric range. The burners and broil world but the oven doesn't. Have changed the element with another and that isn't the problem. Clock and everything else works fine

Below is from the Sears website, you might happen to have the opposite half of the 220 volts working where your clock works and theirs didn't. The other possibility is that a relay or triac (electronic component) on the control board is no longer working.

Thank you for your question and I understand your concern.

Based on your symptom and details it sounds like a problem with the incoming power supply. The line one (L1) voltage supply is not likely supplying the voltage to the clock. When a burner is turned on, the line two (L2) voltage is passing through the burner and switch providing the line one voltage to the clock which will then power up. This could be caused by one of the two house circuit breakers dedicated for the range has tripped or your missing the Line One voltage supply to the range. It could also be an issue with the circuit breaker or the incoming voltage supply to the breaker or wiring issue within the range.

The first thing that should be checked and confirmed is the voltage supply to the range where the power cord is attached. There will be three terminals on the terminal block. The voltage must measure 220-240 volts when measuring across the two outside terminals. The voltage must also measure 110-120 across the center terminal to each outside terminal.

NOTE: I do not recommend measuring voltage unless you have experience and feel safe and confident in doing so; otherwise I strongly recommend calling a service technician to diagnose the failure.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician.

Can the clock spring keep the cruise control from activating . Low voltage to cruise servo .Nothing activates .all fuses good .

Your year--make--model didn't post for some reason? I wanted to look up wiring diagram. I wanted to check voltage to and from steering column for the cruise system.
Where applicable, a clock spring can effect just about anything.

I changed battery, set clock but cannot get the : between the hour and minutes to stop blinking....seems to be losing a little time.

most clocks have the : blinking to show that the clock is working and not in set mode. clocks work of a crystal in the system so that the frequency is set . some clocks have a external device to make small adjustments to clock accuracy. If this is a clock in a vehicle have the voltage to the clock checked as any variation to 12.5 volts will affect the operation of the clock. Any dirty, corroded, loose connections will create a resistance to the current and lower the voltage.

Swimming pool time clock face doesn't move

The timer has internal switches that you connect the input and output to . That is the NO, C , NC set of contacts. It also has a set of terminals for the clock, usually the first terminals on the left. Before connecting a feed to the clock, confirm the voltage rating for the timer. the clock voltage may be different than the contact voltage.

Something burnt inside the clock switched on once back in India. Now it does not work. Could you guide me as to what would be the possible issue now

USA has a standard house voltage of 120 volts @ 60 hz.
Many other countries use higher voltages and/or 50 hz.
If this is the case your clock got fried by high voltage.

The clock resets itself to 12:00 when restarting the 2005 Buick Rendevous. Sometimes if you are really careful how you turn the ignition, the time will stay as set, buy not very often.

maybe you should check your battery condition. the voltage should be 12.3-12.8V. many times the voltage is not enough to cranck the engine and supply all the other devices. Try to turn on the radio and then crank the engine. if the radio stay on and the clock reset then the problem is inside the clocks mechanism. hope helped.

Oven does not work

Open the control panel to expose the clock/oven control.
With a volt meter verify incoming voltage to the clock control.
Check all wires for good contact.
If it still does not work replace the clock.

Remember to unplug the range to check the wires for good contact.
