Modern Vespa

Thank you Vespa for the fiendish design that means replacing the clock battery on my LX only took 2 hours.

Anyway I got it done with a fresh battery but now the clock does not keep the correct time.

I set it with the weird combination of button presses. It displays the correct time. Next day it is out (slow) by over an hour. I thought these clocks were quartz or something and would be accurate. It was fine until the battery failed.

Display is bright and perky so what gives?

Try resetting it again and make sure you do the last step of pushing the button again until you see the : flashing.

Yes maybe that is it. The scoot is not with me at the moment so will have to wait until I get back over to try that.

Thanks

Came back to the bike today and the clock is flashing only showing half the display (horizontal split). Pressing the buttons in sequence stops the flashing for a few seconds but the display is still half horizontal. It seems fritzed. Can I reset the clock any way without removing the battery?
Can a replacement clock be installed?
Just wondering before I embark on the 2 hour simple battery replacement journey.

Hi, did you replace the clock battery as same model as the old one?

A voltage difference can make the quartz crystils to go wrong dramaticly.

I can almost guarantee it's the battery. Mine did the exact same thing when I replaced the battery a while ago. I couldn't figure it out. I ended up bringing the whole dash cluster to a battery store. They tested my "new" batteries that I bought and they were weak. Sold me a different one and the whole thing came to life. Many of these small batteries sit on the store shelf for years before they are sold. Usually the small button batteries do not show an expiration date like more common bigger ones.

Try to find a Renata 386 battery. Just make sure you test it before going through the trouble of replacing it.

Here is a link to the thread that I started looking for a stick on clock but ended changing out the batteries a couple of times. scroll down about halfway.

Stick on clock for LX150ie

after seeing what is involved in replacing the battery and realizing that I need to put my readers on to see it I put an external battery on my Vespa. Much larger and easier to read, and takes about 2 minutes to change the battery. To me a better solution.

OK off come the bits again today and see if I can replace the battery again to get this clock going again. I like the idea of an external battery if I can get the existing clock working again.

Some button cell batteries have a different chemistry with a slightly lower voltage. Typically hearing aid batteries with safer composition are 1.2 to 1.4v. Avoid these.

Install a sun-dial...... permanent fix, maintenance free !!

true but that does require sun

New development. I went to begin taking apart and display is working. I reset the clock making sure to press the top button last to get the colon flashing. Will monitor. Seems weird but I'm leaving things for now.
When I first changed the battery it kept losing time because I did not complete the last step to get the colon flashing. Left for some time like that (month). Maybe that was the cause of the crazy display. Now clock set and has kept perfect time for an hour anyway.

At my age if the clock runs slow that is okay.

Especially the biological clock (-:
