SOURCE: battery fault charge warning on 206 cc 5 years

check charge of battery......put a volt meter across it ,,,should be above 12.3 volts.
2.check to see if alternator is working correctly........put 1 probe on the of alternator and the other probe to the body of the alternator....the reading should be 14v with the car engine running .if not then your alternator needs replacing.
3.with the car running probe your battery...should be reading above 14v.....this means alternator is working .
4.personally i think your battery is not holdng its charge,i would renew it,they cost

Testimonial: "very good was alternator and battery"
