Testing a clock

Post by John »

Before I offer you guys this EK FB clock I have to sell I want to double check its working fine.
Can anyone tell me how to wire it up to test it without killing it?
Not all chemicals are bad. Without chemicals such as hydrogen and
oxygen, for example, there would be no way to make water, a vital
ingredient in beer

The clock assembly is made up of the bakelite outer ring which houses the idiot lights, and the clock mechanism itself (white plastic section in the middle). They are insulated from each other, and the assembly is a little more complex than it first appears. It's easy to short-out the idiot lights if you play with them too much. This will make a mess of your clock - don't ask me how I know :oops:

To test the clock mechanism, connect a 12V positive to the post marked with the + sign on the back of the white clock mechanism casing. Connect a 12V negative to the very outer metal casing of the clock / idiot light assembly. You should hear series of very rapid clicks as the contacts open and close to wind the spring, followed by some nice regular ticking :thumbsup:

It will keep ticking, even after power is removed, until the spring winds down again.

I'll offer you $500 for it (untested). I've fixed a few of these little buggers now and have a fair idea what I'm in for. I'd actually prefer to take it off your hands untested because this will prevent any further possible damage from firing it up without disassembling & inspecting it first.
