Hi all,

I have had my new focus for about two months now and today driving home my battery light came on. I restarted the car and the light came back on so when I got home I opened the bonnet and I could smell burning.

I put the car into test mode and with the car off it reads 12.6V. Once I turn the car on the voltage drops to 12.0V then slowly rises up. After about 30 seconds it reads 13.0V and after a minute or so it reads 14.4V.

Originally I was convinced it was the alternator but now I'm not sure as the voltage is going up to 14.4V.

Has anyone else experienced this problem? I'm thinking along the line of some sort of short?

I did service the car yesterday and changed the fuel filter which is directly on top of the alternator? Could some fuel have got spilled on the alternator causing this problem?

Car is 2009 Ford Focus 2.0 TDCI Titanium X with the 150A alternator due to heated seats.

Thanks,

James
