Hi, '63 4x4 TwinAir. Been doing only short runs over the last couple of weeks in Cold, Wintry conditions, Car left outside, Locked with remote. Came out this morning to completely flat battery, Various warnings about 4x4 not available etc which were not a problem....The wipers were running a very slow intermittent sweep which continued even with key removed, Weird!! Got a jump start which took a while to fire up but car now running fine, all electrics are good. What worried me was the wipers...Had they been going all night to get the battery so low, or was it just a weird happen?? Anybody had this before??
