After having the alternator on my vehicle for just a few months it failed to charge the battery. After initially complaining that it didn’t seem to work I was offered a replacement which didn’t arrive but then it seemed to work so I was at the time not bothered. Now after just a couple of hundred miles it has stopped working completely. Everything else has been checked and a new battery fitted just in case but now I have to buy another alternator. Avoid like the plague unless you want to have to fork out for recovery , battery and a new alternator.
