Why am I getting a battery charge failure warning light in my Rover 75?
I'm having battery charge problems with my Rover 75 CDTi. I get dashboard warnings that all go away when you charge the battery, but return twenty miles afterwards.
Have you checked the state of the battery (i.e. a drop test) to see if the internal state is okay? We would suspect the battery in the first instance. If that's okay then the next check would be the alternator. With the engine running, check the voltage at the battery terminals. You should be getting approximately 12.5 - 13.5 volts, if not then the alternator is faulty.
