Hi all. Im new to these forums. The problem i am having is with my battery not charging up fully after a drive. there was a huge current drain on the battery when the car was off and the interior lights seemed to drain the battery. now that the problem is fixed the battery does not seem to gain any charge its just always just above 50% which means i cant use my alarm or it will drain the battery. Im sure this problem has been posted before but i have tested the charging system and cant find a fault.
