Does 12v clock need voltage regulating

Post by **zippy500** » Sun Jul 16, 2006 12:42 pm

just a quick one.

I am fitting a smiths clock 1970's Does this need voltage regulating. or can i just come a 12v permante supply.

Cheers
Andy

It might be OK off the normal unregulated - I've never had a car where it's driven by the stabilised feed for obvious reasons (the stabiliser is only live with the ignition on).

The clock in my 2000 has a little solenoid which fires when the last jolt of energy has run out - It's pretty much basic clockwork with short burts of "winding" from the solenoid, so input voltage doesn't make any real difference to the time keeping. Not sure if the Smiths one works on the same principle though?

Hello Packed up,

what 2000 is that?

If it's a rover you've just reminded me of the clock thing, I can remember it making a slight noise every now and then. Ah memories!

- hi, I fitted an old vw camper clock to min, no regulator, it runs spot on, no problems....

Not sure what mine is out of. Princess or early Cortina - I think - I can't really remember. It runs fine with an unregulated supply.

Thanks for your replies-Think i'll just come of the battery.

On the subject of dials and regulators-can any1 help I am about to fit a TIM temp gauge-but there is 3 connections on the back as oppose to 2.

They are S-red, G-black and L-green. (the bulb is seperate).... does any1 know how to connect.

Does this have a built in regulator.

Thanks again

Triumph.

Though 2000 suggests it's using all 6 cylinders fully, so maybe 1400 would be closer to the mark with mine

It's also for sale to anyone masochistic enough (needs more than a little work). Which is why I've been quiet on the 2000 board (using a different posting name), got too much else on to be able to keep it anymore, so haven't had any irritating questions to ask ;)

Anyway, back on topic - I've never seen any clock use a regulated feed, but I've had a few that seem to use a small motor to turn the mechanism, like an electric wall clock I suppose. That bothers me as I can't imagine they have a regulator built in. Whereas the Triumph one (Kienzle or something) makes clack ever so often as the solenoid fires, meaning battery charge should make not the least bit of difference - No idea how common a design it is, but it's quite clever I reckon

As for other dials and regulators - I've pretty much only ever used Smiths stuff (scrapyard hunter gatherer me, none of this buy it new malarky) and run it off the stabilised feed so no idea, but I think Onne bought some gauges that had built in whatsits?

My clock runs straight from the battery, no probs.

I did fit a little inline fuse, but that's just me........don't like the idea of any unfused "live" connection.

Then run it from one of the purple wires off the fusebox...

I could have done, but I had one of these clip-on type fuse holders (which holds a blade-type fuse) and I just HAD to use it.
