Hi guys
My alternator packed up about 8 months ago so I bought a new one from my local motor spares place and fit it and everything seemed good, until the other day when I started the car after stopping at the petrol station and could hear a loud whining noise that increased with engine RPM. That noise decided to disappear but as it did, the battery light came on and the battery was reading 12v when the engine was running. So I realised the alternator had stopped charging and managed a few miles before it totally cut out.
My question is, could there be an underlying issue that im not aware of or is it just a faulty/cheap alternator I have bought?
Cheers for any input, I just dont want to replace the alternator if I am missing something that could cause it to go again!
