• Ford Mondeo - Alternator failed, charging circuit 19 Dec 2011 (Forum)
  I'm planning to get it road worthy again, barring any expensive problems being found. It runs well and should be going again shortly. The battery had been charged occasionally, but apparently not regularly enough. It was found to be flat and the car was jump-started but died on disconnecting the good battery. A new battery was obtained and the car starts easily and runs with this.
