Maybe your alternator is not charging! Have you checked the voltage when the engine is running - it must be between 13.8 and 14.2V.

It does not do it all the time and everything is ok charging etc but I Will check it and come back to you thanks

The battery is a dudd -- the AMP output is too low - Try another batery [658 ???] what do you have in your car?

Paul, I suspect either an alternator problem or (possibly more likely) a bad earth connection. Firstly check that the battery clamps are properly tightened, then check all the earth connections.

If you have a multimeter, check the voltage across the battery when the car is running and the warning lights are on?

i agree with Piet bad earth or bad baterry clamps then alternator caint do its job !!
