Ford Focus 1.6tdci 2009 batter light only when heated screen on

Asked by RandomRy Feb 28, 2020 at 08:47 AM about the 2009 Ford Focus

Question type: Maintenance & Repair

Recently battery light came on and stayed on while
driving,  alternator was whining and smelt like
burning electrics so I changed that, since then
although the light doesn't come on straight away it
appears only when heated windscreen is turned
on. I've since changed auxiliary belt and tensioner
also put in a brand new battery.

Have the charging system checked by the shop of your choice, as the charging circuit is controlled by the computer you may have a problem developing there.
