I have ford mondeo 2007 mk4 karavan. I have problem that when I turn on the lights all other lights ( dashboard computer light, radio light) turn very shady and have not so much colour.
Would you say that could be empty battery or something like that ? I tried to drive on high RPMs to charge the battery but it doesnt repair my problem.
Today that I come home I will put battery on charger and see if the problem will be solved or you have some other suggestion how to check if alternator works normally.
Also would like for seccond advice if someone can help. The light for airbags turn off , but never when I start the car, always takes some time... sometimes it doesnt even appear. So can someone suggjest me how to reset this issue so that I can see if there is really some problem ?
Thank you in advance for your answers.
The alternator works properly when the voltage at the battery rises to approx. 14.4 volts immediately after starting the engine. If the voltage is less than 13.8 volts, the battery will not be charged.
