Battery light staying on

Postby gtee » Wed Aug 29, 2018 11:20 am

howsit guys, I need some help pls.

I was driving my fez to work and it just cut out. I started it again but the battery light stayed on. Managed to drive it home again 2km's away.

I've read up online and done some tests with a multimeter.

when the car is off battery reads 12.5v, with it running and no load (Lights etc all off) then it's 14v, with it running and only headlights on then it's 12.5v and running with headlights, ac, demister etc on then it's 12v. (all on the battery).

If I get someone to rev it to 2000 rpm (with no load) then the voltage stays at 14v, it doesn't increase.

There is a whine i've not heard before, but not sure where it's coming from but suspect the alternator.

My concern is I don't want to replace the alternator without being certain that it that cos it's pricey. What do you guys think/advise?

Thanks in advance!

I ended up having to replace the alternator - I used Motorlek in Wynberg Sandton
