Hi all,
I'm hoping you can help me diagnose a potentially dodgy alternator on my girlfriends 2007 grande punto 1.2 (non aircon).
She reported yesterday that the power steering failed to work at the end of a 30-minute drive. I've just had a look at the car and, and tested the battery and found the following:
1) Battery was at 12v when car had been left off (after a separate drive home to the one where the power steering failed).
2) When the car started the voltage rose to 14.3v.
3) With the engine running I turned on the heater to full, lights and rear windscreen demister... The voltage soon dropped to 12v and was continuing to drop... I therefore turned off the heater etc. and the voltage rose to 14v again.
Before I go and book it in for the alternator to be replaced:
Thanks v much, I always find these forums really useful.

Before I go and book it in for the alternator to be replaced:
- Is it clear cut that it's the alternator that's the problem here?
- Are there any recommended garages for this work in South Gloucestershire/Bristol?
- Is there a rough cost I should expect to pay?
