The manufacturer saved the expensive copper wire, easily the most expensive part on the whole clock, by only using half the amount of wire, so the current is very high. Still will work, but now will have a loud tick. With more wire lower current, same magnetic field and lower noise as the current slowly ramps up each pulse. No problem with back EMF anyway as the driver shorts the coil at the end of each pulse to damp the magnet, so there is no EMF at all, and this actually lowers the current flow in the coil during the end of pulse anyway, I also have some clock mechanisms that have been running for a long time, the one has been running for over 30 years, and it is a chiming mechanism, so a replacement one is very much more expensive over the standard mechanism. The mechanism that will benefit the most is the constant sweep ones, where the clock runs at 8 Hz, as these use up a lot of the battery capacity very fast, so you are changing the battery pretty much every 2 months or so on them.

@@SeanBZA Thankyou, i really didnt think about the manufacturer skimping on copper wire. I try not to think in a negative way, makes sense that the cob chip was designed to be forgiving with the inductance current, but people skimping is sadly a bad habit :-(. I have repaired a lot of electronics over the years and t.v sets had a lot of corners cut with component lifetime, i used to repalce parts with uprated ones to keep it going for longer. Capacitors seem to be very low quality in modern sets, skimping again :-(

Wow sir, great. You have learned me many new words! Minimum for me they are new as I'm not an English native speaker. Anyhow I'm trying to learn. Greatly from you. Wonderful. :-D

@@JahanZeb1976 Yes i am english, but i am not the ideal person to learn from, not perfect. I had a lot of trouble learning anything at school, i think i had a faulty brain lol. My english and spelling is not perfect and punctuation is something i guess, so remember that i make mistakes. i learnt electronics in a visual way, the mathmatics and calculations were impossible for me to understand. Learning patterns in circuits and what a circuit does/needs came later. You are far smarter than i will ever be, and that's excellent :-D

@@zx8401ztv Sir your comments are always rock super! They give me energy. Sure I'm learning many new words from you. Always great feeling to see your kind and valued comment.

Nice idea! I need to try that.

Generally poor contact between the battery and the metal contacts, or between the metal battery parts and the copper on the board in the clock. Take apart as shown and clean the contact surfaces carefully with alcohol, and then assemble again and clean the battery contacts and the battery itself. Should help.

@@SeanBZA 👍

i would agree with SeanBZA.. that should fix your problem. if not. Check all the pins the gears are on to see if any has imperfections on them or if any of the gears are missing a tooth or two.(if this is the case scrap it and replace the unit. unless you can replace that particular gear from another clock you might have that you can sacrifice that's the exact same size and tooth number). but SeanBZA's suggestion should fix it up for ya.

What I did with this clock, if you will do with any ordinary clock; an ordinary battery would last for more than a year. Your Duracell may be last for another one more added year!

Hi This process you showed us is not within the scope of diy enthusiasm.

It's just super easy! If you do it once, you will feel it very easy.

@@JahanZeb1976 Sir, yesterday my old i20 key is stuck at ignition ACC. I can't cycle the key to start nor to off position. Key stuck at ACC. I forcibly removed the key and it came out. Till today, same issue. Do I need to replace the whole ignition key cylinder set or only the key??? If so, total prices? Please make videos on how to solve this issue.

Today I would try to shoot a video. This is a very common issue and the solution is way too easy. Let me shoot and post a video.

@@JahanZeb1976 thanks so much for the kind attention👍 Please also mentioned which wires is for ACC, on, start etc particularly to i20 India 1.2 2011. What would be the costs for replacement of ignition key cylinder?? Or do I have to replace the key as well?? Please provide all necessary details if replacement is required.
