Hi..I am trying to sell my 2001 Lotus elise but it has a problem which I hope someone can identify.I have just replaced the battery with a CENTURY DIN44L .I also had the alternator and belt replaced.I imported the alternator from the lotus website in England.Now every so often the battery light comes on and sometimes it will go off on its own and sometimes not till I restart.I took it to an auto electrician who tested it and said it was charging at 13v but dropped to 12.5 when the light were put on.I drove to melbourne (90km) early one morning with the lights on and the battery light was off but as I approached melb the radio suddenly went dead and 5 minutes later the engine cut out and when I tried to start the battery was flat..If anyone has got any ideas I would appreciate the feedback..Regards Steve
