Clock Problem

[goldenfurio]

A did a search but had no return. Well the problem is when a start my car sometimes not all the time the clock will reset its self to 1 dos any1 no what he problem is? thankyou.

[tomgarrett]

itrs probally that all the power from the battery is being used to start the car, which takes the power away from the clock which will cause it to reset

Right well is this a big problem or not and how can it be resolved.

If you can mate check the voltage of the battery. Does your radio also lose ts memory?

[goldenfurio]

no the radio dsnt lose its memory its fine jst the clock.

Get your battery tested.
If it's getting towards the end of it's life, the starter will take as much power as the battery can give to turn the engine over and there's nothing in reserve (voltage wise) to keep anything powered up.
Measure your battery voltage before you touch anything in the morning. You should ideally get a reading of at least 12.5 volts. If you read 12 or less the battery is considered flat and should be recharged or replaced.
Get someone to turn the engine over while you measure the battery voltage with a multimeter. If it drops below 10v while the starter is turning the engine over, then it's time for a replacement (063 is the normal type of battery which is generally used for engines up to 1800cc).
You will need to take the terminal clamps off your old battery by undoing the green and red caps and gently easing the clamps on the battery terminals off with a pair of good levers/biggish screwdrivers and then tapping them onto the new battery.

I'd be surprised if the battery has enough charge to start the car, but not enough to run the clock whilst doing it.

I had a similar problem in my Rallye and traced it back to a fuse which was shorting out. It seemed to work fine, but would lose the clock & std radio memory every time the ignition was turned off. Check all the fuses are pushed in fully.
