Hi - I have a 1989 "F" registered 740 GLE auto Estate which has currently covered about 202 000 miles. It has been continually, but very lightly used since I've owned it (2006 - my dad owned it prior to that for 9 years) - 2000 or 2500 miles per year during which time it's been regularly serviced. Although it is sometimes not used for several weeks, and is parked outside, up till this year (2016) this has not presented any problems. However at the beginning of this year, it became difficult to start - so I had the battery changed in April When this did not resolve the issue (with the new battery having lost all its charge in the space of a few weeks), I then also had the alternator changed. This proved equally ineffective in preventing the battery from losing charge. I've checked obvious things like courtesy lights, but, apart from being advised by a Volvo electrics specialist that he feels it's also unlikely to be the radio, I've run out of ideas as to why it's just not holding any charge. Can you help? By the way, when jump leads deployed, it has no trouble turning and catching virtually immediately.
