Lights (tail/brake, interior, etc) flickering slightly

[Howard-]

Hi all,

I've noticed that my interior, and exterior rear lights on my 2010 Mondeo flicker slightly with the engine running at idle. They don't appear to do it without the engine running and as far as I recall, if you rev it slightly, it stops flickering, but I will confirm later.

There are no other apparent electrical problems or 'gremlins'.

Do I have an alternator or voltage regulator problem?

The other day as I was in the car for a little while fiddling with the audio system I had a low battery warning. Could a dodgy battery cause this?


I'll measure the voltages and check connections etc tonight but I thought I'd start a thread in the mean time in case it's an obvious issue.


Cheers

Thanks. In the engine bay, you would suspect? I'll have a poke around!
