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?
