Battery/Alternator Issue

[DB987654]

Hi all,

I've had a look around the forums and have seen similar posts but thought it best to start a new one with my issue.

About 2 weeks ago, I came to my Focus one morning and it wouldn't start. The battery had gone. Radio came on as I turned the key, but it didn't turn over. Jumped it, and it's been fine since.

This morning, again came to my car to leave for work and exactly the same again.  We jumped it, had a run around for a bit and came back home. Later this afternoon, it didn't start again, but after a few attempts it finally did without being jumped. Since then, it's started a few times this afternoon with no issue.

We've had the battery checked this afternoon and it tests fine.

Would the next step be having the alternator checked? I've been told today that alternators failing can give out a whirring noise, which come to think of it has been happening on and off for a few months but we've though nothing of it.

It's a Focus zetec 2010 59 plate (2009).

It'll be next week now before I can get to a garage. In the mean time, and to prepare me for costs, Is this the most likely culprit and does the whirring noise sound like it could be related?

Thanks all!

My alternator started making a whirring noise one day. The next day it was so hot that it was glowing red. Nearly caught fire. £220 later and all is good. Just get it replaced. Don't question it.

That's how mine went at first couldn't determine if it was the alternator or turbo on and off for months then like you battery died would not start (cold day) so plumped for a new battery put it on and within a minute the alternator was almost on fire smoke bellowing everywhere turned out it was that all along luckily enough got away with any further damage been ok since change even the little electrical gremlins have disappeared my radio/ satnav was doing weirded things again ok now hope this helps
