have a slow drain 1.3 amps battery goes flat every 2 weeks could it be [A ] the clock the radio not a Volvo radio and also not connected to ignition.any one had this problem car fully charges battery after a short run

cheers jack m

Perhaps borrow another battery? There's not much on a 300 which can drain it. How old is the battery?

brand new battery off to auto elctrician today ,, thanks

Could a bad earth cause this? I know I have a battery drain somewhere but it's very likely that it's just the appalling state of my positive lead causing high resistance. It's not bad enough for me to fix it though

just back from auto elect checked radio and clock he thinks the drain i have should not flatten battery ,, thanks guys one of those gremlins i geuss? roll well

A bad earth could cause the drain. May be a loose or corroded earth or one connected in the wrong place i.e. connected to alloy.

battery was faulty was brand new problem solved thanks for all your input
