My youngest (only passed his test a week or so back) went to start the corsa (C, 1.2 petrol, 53 plate) virtually dead.
He got taken where he was going in another car and I got it onto charge.
It then started fine, went for a drive, and battery light came on and battery low when it got home again.
Charged it up again (mostly) and went away for a couple of days.
Some diags yesterday.
12.2v sat on the drive
dropped a bit with electrics on
down to about 10 cranking
back up to 12.1 at idle, or fast idle with load, not much difference.
No obvious heat in battery cables, looked no further than that yet.
So at this point to me its pointing at the alternator, low output.
Is this guide likely to apply to a Corsa alternator does anyone know? https://www.omegaowners.com/forum/index.php?topic=90512.0
Or am I best just replacing it, any caveats if I do the job, access doesnt look great fun and theres a bloody great spring tensioner in the way too.

Sounds like the alternator, the one on the Corsa is the open framed Bosch version as per the later 2.6/3.2, it probably is the regulator but, you need the Bosch regulator part number to get the right one
-
Assuming I can get it off ok, we can manage without it for a few days whatever I need to get
-
Right, its on the bench....
Do we think I just replace this part?

With something like https://www.ebay.co.uk/itm/186655955645/ (https://www.ebay.co.uk/itm/186655955645/) Any makes to go for / avoid?
This is where that connects in to

Or do I just get a new one like these? https://www.autodoc.co.uk/ridex/15231132

For £96 I know what I'd do, but I'm anything for the quickest fix with the least hassle.

I would save £76 ish and buy the part for the alternator. :y
And then curse when it didn't work once I'd refitted it! ;D

That looks the same as the Omega regulators and it was always the regulator on those. Got several of them from these guys back in the day https://www.rotatingelectrics.co.uk/ (https://www.rotatingelectrics.co.uk/).
EDIT: Worth checking the bearings while you're at it. Those are an easy and cheap replacement if they aren't great.

Well wasn’t over keen on the spin. Thanks for the heads up. So with the cost and time of fixing both… I grabbed one from the local factors and got it fitted after work. Bit of fun getting the tensioner and belt back on but all done and charging up again at proper voltage. Thanks all. Kids have their car back and no more taxi-ing. Well worth the small premium.
