Hiya Ed, Sounds to me like a dead battery, suggest you take along a new one when you go back to the car. Its possible the battery is just past its use-by date (about 18 months to three years depending) or there is a drain like a trunk light or glovebox light or somethig else that's staying on. Also check and correct all earths in case there isn't a full circuit for the charge to occur. If the alternator or the voltage regulator aren't working, this would also cause a flat battery. If you have the dough, get an auto-electrician to check the car over. Old cars, eh...who'd have 'em? Best of luck. Pete.
