Flat Battery?

I don't know but it feels like the battery is in good shape when she starts the car . I have not tested the alternator yet with an multimeter , maby the alternator is overcharged ? How much should it charge : 14,8 v ?

power steering light intermittent, normally means battery on way out

or on occassion a bad earth or the wires on the front of the gearbox broken (usually that caused flat battery)

Ok , i Will check that . Feels good to know where i Can begin to seek the problem . Thank's so much for helping . I Will reply if i found the problem . Peter .

Steering wheel angle sensor or steering wheel pump can also be controlled

Hello , i repaced The battery and it runs normaly again :-D . The old battery was bad condition . Thank's so much for the help iv'e got from here !
