I have a 92 318i and I've have searched all over the place here and Google for help before posting. The battery(second new one) will not hold charge and when it does it last for an hour or so I've pulled every fuse one by one while doing parasitic drain test with multimeter and only one that make a very little difference is ac compressor so I left it out I've pulled individual parts(radio,amp,climate control,window switches,trunk and hood light) I have also checked trunk wiring and there good. Now yesterday I decide to get a jump start and I got a blast of rotten egg smell and can hear bubbling from battery while car was running I've seen mixed answers on if that's bad or not.i just want to know if there is anyone else who had this issue and can tell me if I missed something or how they fixed theres.thanks in advance(local auto store attempted to check alt and batt but there machine couldn't detect voltage on either batt post or under hood post so alt check never happened possible voltage regulator bad maybe)
