    I assume you've checked that the belt isn't loose?

    Yes the belt is fine looks like it’s an intermittent fault I had a meter on the battery today and sometimes it’s reading 14.1 then back to 12.6 Honda want £450 to replace it.

    Looks like the alternator is fine, I tested it again today when I started the car the battery was reading 14.1v after about 15 mins that dropped to 12.6 if I then put the air con on the alternator would kick back in and the battery would read 14.1 again I did this several times always the same result.

    It seems more likely that it is either a loose connection ( so check these) or it is the voltage controller that's located in the fusebox. I can't remember the correct name for it, but it basically tells the alternator when to increase alternator output.

    However when was the battery last changed, as they usually only last a max of 5-6 years before needing a replacement. And add to this, if your car has Bluetooth, it may have the renowned Bluetooth battery drain issue.

    Highly likely to be the HFT causing the paralytic drain. It is a well known issue as the system ages.
