Just a quick check before I try and diagnose further.

The battery light stays on for roughly the 1st 10 min of the car running, and only if its the first journey of the day or there has been a good 4 / 5 hours since the last run.

I had suspicions of the battery being worn out so replaced that, but this hasn't rectified the issue. I haven't yet put a multimeter (as I have lost mine) across the terminals when the light is on to see what volts are there but will do next time it happens. Got to work and checked it, but the light was off by then and there was 13.8v showing as one would expect.

I just wanted to know if this is something that has happened to other people and what the issue was, alternator wearing out, lose belt, anything really??

Thanks in advance!

Moderators - I have opened this topic in the Drivetrain section as well, hoping for answers.
