Guest another Ratman Posted November 24, 2011 Share Posted November 24, 2011 Can a 6vdc car clock be tested with a 9 volt battery if a 6 is not available. A seller on ebay has a clock and no 6vdc battery to test with, only a 9volt. I told him to hang on while I get a answer and don't do it till I get back to him. Thanks much....and happy Thanksgiving!

Guest Jim_Edwards Posted November 24, 2011 Share Posted November 24, 2011 Given most all old automotive clocks were electric rewind mechanism and not motor driven momentary contact with a 9V battery will probably not hurt anything and will rewind the clock. Momentary meaning just touching the wires to the battery terminals for a fraction of a second. Link to comment Share on other sites More sharing options...
Bleach Posted November 24, 2011 Share Posted November 24, 2011 I used to test various automotive electrical components with a 6/12V battery charger.Do so at your own risk. Link to comment Share on other sites More sharing options...
Guest 89 Maui Posted November 24, 2011 Share Posted November 24, 2011 Simply take 4 "AA" batteries end on end (plus to minus) and you will have 6 VDC. This will will check your 6 volt clock.Woody89 Maui Link to comment Share on other sites More sharing options...
Rusty_OToole Posted November 25, 2011 Share Posted November 25, 2011 A 6 volt car battery, fully charged, puts out 6.6V or a little more. With the engine running and the generator working, system voltage is at least 7.2.So 9 volts is not much above the working voltage of the clock. If the 9 volt battery is a little worn down it may only have 8 volts or less anyway.In other words, a 9 volt battery will not hurt the clock in the slightest if it is not shot to begin with.

ply33 Posted November 25, 2011 Share Posted November 25, 2011 I wonder if a 9v "transistor battery" can source enough current to actually drive the clock mechanism... Link to comment Share on other sites More sharing options...

Bhigdog Posted November 25, 2011 Share Posted November 25, 2011 Ply 33 hits the BINGO button. A battery charger is good test source. The rewind coil in the clock is a far cry from delicate electronics and a 1/4 second jolt from a 12 volt battery should not hurt it. Do be aware though. As with any piece of electrical gear a certain amount of smoke was put in it at the factory. This smoke is essential for satisfactory operation and if you let the smoke out it won't work so good................Bob Link to comment Share on other sites More sharing options...
Guest Jim_Edwards Posted November 25, 2011 Share Posted November 25, 2011 I wonder if a 9v "transistor battery" can source enough current to actually drive the clock mechanism...Car clocks are usually electric rewind, which is to say there only has to be enough momentary current to excite a coil winding sufficiently to rewind the spring which will then drive the clock mechanism.A successful rewind does not mean the clock will be functional. Old lubricant gets hard and gears fail to turn. If an old car clock doesn't work properly it probably just needs a cleaning and fresh lubricant. Even a Caveman could do it.

Guest Bob Call Posted November 25, 2011 Share Posted November 25, 2011 To clean the clock works, put the works in an airtight container with a wad of cotton saturated with kerosene and let is sit for a couple of weeks. The kersoene vapor will soften and dissolve the old lube. Lube the works at each bearing or "jewel" point with a light lube like 3 In One oil with a pin or toothpick so each lube point gets only a fraction of a drop.

Guest another Ratman Posted November 25, 2011 Share Posted November 25, 2011 Wow! I knew I would have a PHD's worth of information come back for this question. A heartfelt thanks for all the information. I will contact the seller and give it a try,. Thanks again everyone. Even Bhigdog helped with some little known factory info. I think the smoke is filtered through the double mutterer. God bless all and, LOOK TWICE, SAVE A LIFE. Ratman Link to comment Share on other sites More sharing options...

Guest prs519 Posted December 4, 2011 Share Posted December 4, 2011 I always let it out (the smoke), too. Seems like it has been nothing but trouble for me.Perry Link to comment Share on other sites More sharing options...
1937hd45 Posted December 4, 2011 Share Posted December 4, 2011 Thought frying it with the battery charger was the best answer. Link to comment Share on other sites More sharing options...
Guest Dick Whittington Posted December 5, 2011 Share Posted December 5, 2011 I have had trouble in the past in keeping the factory smoke encased in several devices.Must be Lucas as anything equipped with Lucas components has a terrible time trying to keep the smoke from escaping all the wiring and components Link to comment Share on other sites More sharing options...

Guest notnow Posted December 8, 2011 Share Posted December 8, 2011 Go to Walmarts and get a 6volt lantern Battery.A cheap one only cost about $4 ..I use one to test a lot of 6volt items.. Link to comment Share on other sites More sharing options...
Guest another Ratman Posted December 12, 2011 Share Posted December 12, 2011 Once again thanks for the chuckles and great answers. As a M.G. owner I know all about the Lucas smoke. By the way roadside shoulder gravel/dirt is not very effective in containing Lucas smoke either, even a couple of inches won't do it. I swear it was my buddy Bear that tried that one.

roadfossil Posted December 23, 2011 Share Posted December 23, 2011 I own a car clock repair business. Yes you can run a 6v car clock on 12v temporairly. Some types of 6v electric clocks can be run forever on 12v. Not all electric car clocks are built the same way nor work on the same principle.

roadfossil Posted December 24, 2011 Share Posted December 24, 2011 As a professional Clocksmith specialising in car clocks, I always get a kick out of reading peoples answers/solutions to clock questions. I may compile them and write a book someday. Link to comment Share on other sites More sharing options...
