What does it mean when your clocks do a full sweep?

[HD-Aye!]

As per title really, aint driven the car for a week as I was away. The last two times I turned the ignition on, all of the clocks do a full sweep. Including temp and fuel and the oil pressure. Anybody know what this means?

[DeeTurbo]

Isn't that an earth fault?

[Matt]

Or a battery issue

[Toms306]

Usually a low battery or crap terminal in my experience.

[HD-Aye!]

Sounds about right, I had been away for a week so battery was prob low. Its not doin it anymore

[Niall]

Yep that usually indicates a lower than normal cranking voltage. 9 times out of 10, thats a battery on its way out but can also be an earth fault of bad wiring.

I also had this on mine but never got round to sorting it.

[daddyfixit]

quite common; its called capacitance------disconnect both battery leads and touch them together, refit them to the battery and that's it.
